No Retry-after in header

Question

Hi
I have just 2 questions.

When I have an error, for exemple : The operation failed because the request was throttled.

Its normal i don't have Retry-after in the header ?

And how to make the API call not encounter this problem because I wait X seconds is always the same problem in the following API call ?

My call : POST /me/drive/items/{item-id}/invite

Regards

Answer 1

Hello @Nadjim , the Retry-After is not always included in a response. ** If no Retry-After header is provided by the response, **we recommend implementing an exponential backoff retry policy. You can also implement more advanced patterns when building large-scale applications.

Microsoft Graph SDKs available for 7 programming languages already implement handlers that rely on the Retry-After header or default to an exponential backoff retry policy.

Hi @Nadjim ,
Per my research, I do agree with alfredorevilla-msft's answer. The Retry-After is not always included in a response. When we get 503 error there may be a Retry-After header in response.
