HTTP V2 API

Use the HTTP V2 API to send data directly from your server to the HTTP V2 endpoint.

The HTTP V2 API replaces the deprecated HTTP API.

Get interactive examples for this API

The Amplitude Developers Postman profile has a collection of the example requests included in this documentation, including detailed responses for each call. You don't need a Postman account to browse.

If you already use Postman, you can fork and run the collection in Postman.

Getting started¶

Use this quickstart guide to get started with Amplitude HTTP V2 API.

Authorization¶

This API doesn't use authorization, but uses your API key. Pass your API key in the body of the request like api-key={{api_key}}.

See Find your Amplitude Project API Credentials for help locating your credentials.

Endpoints¶

For EU data residency, the project must be set up inside Amplitude EU. Remember to use the EU residency endpoint in all HTTP requests.

Region	Endpoint
Standard Server	https://api2.amplitude.com/2/httpapi
EU Residency Server	https://api.eu.amplitude.com/2/httpapi

Considerations¶

Upload limit¶

For Starter plan customers:

Limit your upload to 100 batches per second and 1000 events per second. You can batch events into an upload, but don't send more than 10 events per batch. Amplitude expects fewer than 100 batches per second, and the 1000 events per second limit still applies.

For customers on Growth and Enterprise plans:

Contact Support if you need to send more than 1000 events per second. There is no hard limit on the Enterprise plan, but devices that exceed 30 events per second are throttled.

Keep request sizes under 1 MB with fewer than 2000 events per request. When you exceed these size limits, you get a 413 error.

If you have high volume and concerned with scale, partition your work based on device_id or user_id. This ensures that throttling on a particular device_id (or user_id) doesn't impact all senders in your system. If you are using a proxy service to send events to Amplitude, make sure that throttling is forwarded to your clients, instead of letting spammy clients slow down a partition of work in your system.

Information for partner integrations¶

If you have an event ingestion integration with Amplitude, you need to send your integration's assigned partner ID in the event payload.

For help finding your integration's partner ID and a payload example, see Create an Event Ingestion Integration.

All-zero device IDs: Limit Ad Tracking enabled¶

As of iOS 10, Apple replaces the Identifier for Advertiser (IDFA) with all zeros if the user enables Limit Ad Tracking. Because all events require a device ID, Amplitude drops device IDs of all zeros and returns an error on the request.

If you are passing the IDFA as the device ID, first run a check on the IDFA value. If it's all zeros, pass a different value for the device ID, such as the Identifier for Vendor (IDFV).

Windows OS¶

If you are using a Windows operating system, then you may have to replace all single quotes with escaped double quotes.

String character limit¶

All string values, like user_id, event, or user property values, have a character limit of 1024 characters.

Set date values¶

Amplitude compares dates as strings, so it's best to use the ISO 8601 format (YYYY-MM-DDTHH:mm:ss). This format lets you perform date comparisons, (for example: '2016-01-31' > '2016-01-01'). Comparison also works for datetime values in this format (for example: '2017-08-07T10:09:08' > '2017-08-07T01:07:00').

Set time values¶

You must send the time parameter in each event as millisecond since epoch. Any other format (such as ISO format) results in a 400 Bad Request response.

Event deduplication¶

It's highly recommended that you send an insert_id for each event to prevent sending duplicate events to Amplitude. Amplitude ignores subsequent events sent with the same insert_id on the same device_id (if the event has a device_id value) in each app within the past 7 days.

Device IDs and User IDs minimum length¶

Device IDs and User IDs must be strings with a length of 5 characters or more. This is to prevent potential instrumentation issues. If an event contains a device ID or user ID that's too short, the ID value is removed from the event.

Override the default minimum length of 5 character by passing the min_id_length option with the request.

If the event doesn't have a user_id or device_id value, the upload may be rejected with a 400 status.

Invalid IDs (click to expand)

These IDs are invalid, and result in a 400 error:

"anonymous"
"nil"
"none"
"null"
"n/a"
"na"
"undefined"
"unknown"

"00000000-0000-0000-0000-000000000000"

Keys for the event argument¶

You can send these keys in the JSON event object. Note that one of user_id or device_id is required, as well as the event_type.

Name	Description
`user_id`	Required if `device_id` isn't used. String. ID for the user. Must have a minimum length of 5 characters unless overridden with the `min_user_length` option.
`device_id`	Required if `user_id` isn't used. String. A device-specific identifier, such as the Identifier for Vendor on iOS. If a `device_id` isn't sent with the event, then it's set to a hashed version of the `user_id`.
`event_type`	Required. String. A unique identifier for your event. The following event names are reserved for Amplitude use: `[Amplitude]` Start Session", `[Amplitude]` End Session", `[Amplitude]` Revenue", `[Amplitude]` Revenue (Verified)", `[Amplitude]` Revenue (Unverified)", and `[Amplitude]` Merged User". Note: `$identify` and `$groupidentify` are predefined for identification and group identification.
`time`	Optional. The timestamp of the event in milliseconds since epoch. If time isn't sent with the event, then it's set to the request upload time.
`event_properties`	Optional. Object. A dictionary of key-value pairs that represent data to send along with the event. You can store property values in an array. Date values are transformed into string values. Object depth may not exceed 40 layers.
`user_properties`	Optional. Object. A dictionary of key-value pairs that represent data tied to the user. You can store property values in an array. Date values are transformed into string values. Object depth may not exceed 40 layers.
`groups`	Optional. Object. This feature is only available to Enterprise customers who have purchased the Accounts add-on. This field adds a dictionary of key-value pairs that represent groups of users to the event as an event-level group. You can track up to 5 unique group types and 10 total group values per event. Any groups past that threshold aren't tracked.
`group_properties`	Optional. Object. This feature is available only to customers who have purchased the Accounts add-on. When "event_type" is `$groupidentify`, the field is a dictionary of key-value pairs that represent properties tied to the groups listed in the "groups" field. The field is ignored for other event types. Group property operations (`$set`, `$setOnce`, `$add`, `$append`, `$unset`) are also supported.
`$skip_user_properties_sync`	Optional. Boolean. When `true` user properties aren't synced. Defaults to `false`. See Skip user properties sync for more information.
`app_version`	Optional. String. The current version of your application.
`platform`	Optional. String. Platform of the device.
`os_name`	Optional. String. The name of the mobile operating system or browser that the user is using.
`os_version`	Optional. String. The version of the mobile operating system or browser the user is using.
`device_brand`	Optional. String. The device brand that the user is using.
`device_manufacturer`	Optional. String. The device manufacturer that the user is using.
`device_model`	Optional. String. The device model that the user is using.
`carrier`	Optional. String. The carrier that the user is using.
`country`¹	Optional. String. The current country of the user.
`region`¹	Optional. String. The current region of the user.
`city`¹	Optional. String. The current city of the user.
`dma` ¹	Optional. String. The current Designated Market Area of the user.
`language`	Optional. String. The language set by the user.
`price`	Optional. Float. The price of the item purchased. Required for revenue data if the revenue field isn't sent. You can use negative values for refunds.
`quantity`	Optional. Integer. The quantity of the item purchased. Defaults to 1 if not specified.
`revenue`	Optional. Float. Revenue = (price x quantity). If you send all 3 fields of price, quantity, and revenue, then the revenue value is (price x quantity). Use negative values for refunds.
`productId`	Optional. String. An identifier for the item purchased. You must send a price and quantity or revenue with this field.
`revenueType`	Optional. String. The type of revenue for the item purchased. You must send a price and quantity or revenue with this field.
`location_lat`	Optional. Float. The current Latitude of the user.
`location_lng`	Optional. Float. The current Longitude of the user.
`ip`	Optional. String. The IP address of the user. Use `$remote` to use the IP address on the upload request. Amplitude uses the IP address to reverse lookup a user's location (city, country, region, and DMA). Amplitude can drop the location and IP address from events after they reach Amplitude servers. Contact the Support team to configure this.
`idfa`²	Optional. String. (iOS) Identifier for Advertiser.
`idfv`	Optional. String. (iOS) Identifier for Vendor.
`adid`²	Optional. String. (Android) Google Play Services advertising ID

`session_id`	Optional. Long. The start time of the session in milliseconds since epoch (Unix Timestamp), necessary if you want to associate events with a particular system. A `session_id` of -1 is the same as no `session_id` specified.
`insert_id`	Optional. String. A unique identifier for the event. Amplitude deduplicates subsequent events sent with the same `device_id` and `insert_id` within the past 7 days. Amplitude recommends generating a UUID or using some combination of `device_id`, `user_id`, `event_type`, `event_id`, and time.
`plan`	Optional. Object. Tracking plan properties. Amplitude supports only branch, source, version properties.
`plan.branch`	Optional. String. The tracking plan branch name. For example: "main".
`plan.source`	Optional. String. The tracking plan source. For example: "web".
`plan.version`	Optional. String. The tracking plan version. For example: "1", "15".

Options¶

Name	Description
`min_id_length`	Optional. Integer. Overrides the default minimum length of 5 for `user_id` & `device_id` fields.

Response format¶

It's best practice to implement retry logic and send an insert_id (used for deduplication of the same event) in your events. This prevents lost events or duplicated events if the API is unavailable or a request fails.

200 response SuccessSummary¶

200 OK: Successful real time event upload. If you don't receive a 200 OK response, retry your request.

{
  "code": 200,
  "events_ingested": 50,
  "payload_size_bytes": 50,
  "server_upload_time": 1396381378123
}

Properties¶

Name	Description
`code`	Integer. 200 success code
`events_ingested`	Integer. The number of events ingested from the upload request.
`payload_size_bytes`	Integer. The size of the upload request payload in bytes.
`server_upload_time`	Long. The time in milliseconds since epoch (Unix Timestamp) that Amplitude's event servers accepted the upload request.

400 response InvalidRequestError¶

400 Bad Request. A 400 indicates invalid upload request. Check the response for more information.

Possible reasons for an invalid request:

The request body isn't valid JSON. The error returned is "Invalid JSON request body".
The request body is missing required fields. The error returned is "Request missing required field", and indicates which fields are missing.
The events object has invalid fields. events_with_invalid_fields maps field names to an array of indexes indicating the events with invalid values.
Some devices have been silenced.

429 response TooManyRequestsForDeviceError¶

429 Too Many Requests. Too many requests for a user or device. Amplitude throttles requests for users and devices that exceed 30 events per second (measured as an average over a recent time window). You should pause sending events for that user or device for a period of 30 seconds before retrying and continue retrying until you no longer receive a 429 response.

  "code": 429,
  "error": "Too many requests for some devices and users",
  "eps_threshold": 30,
  "throttled_devices": {

}

Properties¶

Name	Description
`code`	Integer. 429 error code
`error`	String. Error description.
`eps_threshold`	Integer. Your app's current events per second threshold. If you exceed this rate your requests are throttled.
`throttled_devices`	Object. A map from `device_id` to its current events per second rate, for all devices that exceed the app's current threshold.

`throttled_events`	Array of indexes in the events array indicating events whose `user_id` or `device_id` were throttled.

Server Error 500, 502, 504¶

500, 502, and 504 Server Error. Amplitude encountered an error while handling the request. A request with this response may not have been accepted by Amplitude. If you retry the request, it could duplicate the events. To avoid duplication, send an insert_id in your requests.

503 Service Unavailable¶

503 Service Unavailable. Request failed because of an internal Amplitude issue. Retrying a request with a 503 response doesn't risk duplicating events.

[Amplitude] Country, [Amplitude] City, [Amplitude] Region, and [Amplitude] DMA are user properties pulled using GeoIP. Amplitude uses MaxMind's database, which is widely accepted as the most reliable digital mapping source, to look up location information from the user's IP address. For any HTTP API events, if GeoIP information is unavailable, then Amplitude pulls the information from the location_lat and location_lng keys if those keys have values. If the location properties are manually set, then Amplitude doesn't change that property. ↩↩↩↩
These values appear as null in Amplitude. For privacy reasons, Amplitude processes the attribution information, but strips the values before saving the event in the system. ↩↩
