![]() ![]() ![]() Identify the throttling limits that apply for each Microsoft Graph resource.If SDKs retry throttled requests automatically when they are not batched, throttled requests that were part of a batch are not retried automatically. You may retry all the failed requests in a new batch after the longest retry-after value. You should retry each failed request from the batch using the value provided in the retry-after response header from the JSON content. It is possible for multiple requests to be throttled in a single batch. The batch itself fails with a status code of 424 (Failed Dependency). Client library versions always share the Major and Minor numbers of the API version they support, followed by a third number (usually called the Patch number) that represents the revision of the sdk internal code. Requests in a batch are evaluated individually against throttling limits and if any request exceeds the limits, it fails with a status of 429 and an error similar to the preceding sample response. X-Api-Version: v3.6 The Changelog is available below. JSON batching allows you to optimize your application by combining multiple requests into a single JSON object. Continue to use the recommended Retry-After delay and retry the request until it succeeds.Īll the resources and APIs described in the Service-specific limits provide a Retry-After header except when noted.įor a broader discussion of throttling in the Microsoft Cloud, see Throttling pattern.īest practices for discovering files and detecting changes at scale describes best practices in details. If the request fails again with a 429 error code, you are still being throttled. ![]() Wait the number of seconds specified in the Retry-After header.Backing off requests using the Retry-After delay is the fastest way to recover from throttling because Microsoft Graph continues to log resource usage while a client is being throttled. The failed response includes the Retry-After response header. I've tried calling and emailing since, but haven't got a response or an answer. I've spoken to them on the phone and the call rep said she couldn't do anything, and said they would forward on to an engineer (Feb. When you implement error handling, use the HTTP error code 429 to detect throttling. I originally opened my support ticket with robinhood on Feb 6th. Avoid immediate retries, because all requests accrue against your usage limits.Reduce the number of operations per request.The following are best practices for handling throttling: Whenever the throttling threshold is exceeded, Microsoft Graph responds with a response similar to this one. A large number of requests from a particular application across all tenants.A large number of requests across all applications in a tenant.The most common causes of throttling of clients include: Therefore, you could encounter a scenario where writes are throttled but reads are still permitted. ![]() Threshold limits vary based on the request type. For example, if you have a high volume of requests, all requests types are throttled. Throttling behavior can depend on the type and number of requests. A suggested wait time is returned in the response header of the failed request. When throttling occurs, Microsoft Graph returns HTTP status code 429 (Too many requests), and the requests fail. One solution is to have a minimum interval of time between two consecutive actions, and take actions in the same order as they were requested.When a throttling threshold is exceeded, Microsoft Graph limits any further requests from that client for a period of time. You could even have threads waiting forever, in my point of view. If multiple threads are blocked waiting for a token, it is not clear which one will take the next available token. The DelayedQueue has a disadvantage: the order at which threads request tokens might not be the order at which they get their request fulfilled. you want to limit 10 actions per 10 seconds but you don't want 10 actions to happen in the first second and then remain 9 seconds stopped). Imagine the case in which multiple threads want a token to do some globally rate-limited action with no burst allowed (i.e. ![]()
