102 Processing

What does 102 Processing mean?

The server has accepted the request but has not yet completed it. It belongs to the 1xx Informational class, which means the request was received and the process is continuing. These are interim responses you rarely handle directly.

When do APIs return 102?

WebDAV servers use it to keep a client from timing out during a long operation.

How to fix a 102 Processing

Informational only. Ensure your client timeout is long enough for the real response to arrive.

Reproduce a 102 response

The fastest way to understand a status code is to trigger one and read the full response. Open the API tester and send a request to https://httpbin.org/status/102 — you will see the 102 status along with every response header the server sent. Comparing those headers against a working request is often what reveals the cause.

When you are debugging a real endpoint, check the response headers as carefully as the body, and confirm you are using the right HTTP method for the operation.
