Events API

The Events API allows you to ingest JSON events with a simple HTTP POST request. See Events API.

All endpoints require authentication using a Token with DATASOURCE:APPEND or DATASOURCE:CREATE scope.

POST /v0/events

Use this endpoint to send NDJSON (new-line delimited JSON) events to a Data Source.

### Request parameters

Key Type Description
nameStringname or ID of the target Data Source to append data to it
waitBoolean'false' by default. Set to 'true' to wait until the write is acknowledged by the database. Enabling this flag makes possible to retry on database errors, but it introduces additional latency. It's recommended to enable it in use cases in which data loss avoidance is critical. Disable it otherwise.

### Return HTTP status codes

Status Code Description
200The data has been inserted into the database. The write has been acknowledged. The request 'wait' parameter was enabled.
202The data has been processed, and it will be send to the database eventually. The write hasn't been acknowledged yet. The request 'wait' parameter was disabled.
400The request is invalid. The body will contain more information. A common cause is missing the 'name' parameter. No data has been inserted, but the request shouldn't be retried.
403The token isn't valid. The request shouldn't be retried.
404The token's Workspace doesn't belong to this cluster. The Workspace is probably removed or in another cluster. The request shouldn't be retried, ensure the token's region and the Tinybird domain matches.
422The ingestion has been partially completed due to an error in a Materialized View. Retrying may result in data duplication, but not retrying may result in data loss. The general advice is to not retry, review attached Materialized Views, and contact us if the issue persists.
429The request/second limit has been reached. Default limit is 1000 requests/second, contact us for increased capacity. The request may be retried after a while. Use exponential backoff with a limited amount of retries.
500An unexpected error has occurred. The body will contain more information. Retrying is the general advice, contact with us if the issue persists.
503The service is temporarily unavailable. The body may contain more information. A common cause is to have reached a throughput limit, or to have attached a Materialized View with an issue. No data has been inserted, and it's safe to retry. Contact with us if the issue persists.
0x07 GOAWAYHTTP2 only. Too many alive connections. Recreate the connection and retry.

### Compression

You can compress JSON events with Gzip and send the compressed payload to the Events API. You must include the header Content-Encoding: gzip with the request.

Examples

NDJSON messages

The following example shows how to push single NDJSON messages using the Events API:

Send individual NDJSON messages
curl \
    -H "Authorization: Bearer <import_token>" \
    -d '{"date": "2020-04-05 00:05:38", "city": "Chicago"}' \
    'https://api.tinybird.co/v0/events?name=events_test'

JSON messages

The following example shows how to push single JSON messages using the Events API:

Send individual JSON messages
curl \
    -H "Authorization: Bearer <import_token>" \
    -d $'{ \
          "date": "2020-04-05 00:05:38", \
          "city": "Chicago" \
        }' \
    'https://api.tinybird.co/v0/events?name=events_test&format=json'

Multiple NDJSON messages

The following example shows how to push multiple NDJSON messages using the Events API. Notice the '$' before the JSON events. It's needed in order for Bash to replace the '\n'. curl doesn't do it automatically.

Send many NDJSON events.
curl \
    -H "Authorization: Bearer <import_token>" \
    -d $'{"date": "2020-04-05 00:05:38", "city": "Chicago"}\n{"date": "2020-04-05 00:07:22", "city": "Madrid"}\n' \
    'https://api.tinybird.co/v0/events?name=events_test'

Gzip compressed payload

The following example shows how to push a Gzip compressed payload using the Events API, where 'body.gz' is a batch of NDJSON events.

Send a Gzip compressed payload.
curl \
    -H "Authorization: Bearer <import_token>" \
    -H "Content-Encoding: gzip" \
    --data-binary @body.gz \
    'https://api.tinybird.co/v0/events?name=events_example'
