API: Attachments
Use the following API methods to upload, retrieve and delete attachments.
The following headers must be used when uploading attachments via the TestRail API using POST requests:
| Content-Type | multipart/form-data |
The attachment should be submitted as form-data in the body of the request. Please review our Accessing the API documentation or TestRail’s bindings for examples of submitting an attachment.
On this page:
API Rate Limit
Please note that the API is rate-limited on TestRail Cloud to ensure optimal performance for all users and may throttle requests. TestRail might also return a 429 Too Many Requests response, which you are expected to handle. Such a response also includes a Retry-After header indicating how many seconds to wait before you are allowed to submit the next request.
To avoid rate limits on TestRail Cloud, try using bulk API endpoints (e.g. using as add_results_for_cases instead of add_results_for case), build a time delay into your API calls, or upgrade to TestRail Enterprise Cloud.
Rate limits for TestRail Cloud are as follows:
-
180 Requests per instance, per minute for TestRail Cloud Professional subscriptions.
-
300 Requests per instance, per minute for TestRail Cloud Enterprise subscriptions.
No API rate limits are built into TestRail Server installations.
