Write data with the InfluxDB API
Write data to InfluxDB using an HTTP request to the InfluxDB API /api/v2/write endpoint.
Use the POST request method and include the following in your request:
| Requirement | Include by |
|---|---|
| Organization | Use the org query parameter in your request URL. |
| Bucket | Use the bucket query parameter in your request URL. |
| Timestamp precision | Use the precisionquery parameter in your request URL. Default is ns. |
| API token | Use the Authorization: Token YOUR_API_TOKEN header. |
| Line protocol | Pass as plain text in your request body. |
Send a write request
The URL in the examples depends on the version and location of your InfluxDB 2.7 instance. Customize URLs in examples

Use gzip compression with the InfluxDB API
When using the InfluxDB API /api/v2/write endpoint to write data, compress the data with gzip and set the Content-Encoding
header to gzip.
Compression reduces network bandwidth, but increases server-side load.
