# Error handling
|
|
|
|
Zulip's API will always return a JSON format response.
|
|
The HTTP status code indicates whether the request was successful
|
|
(200 = success, 40x = user error, 50x = server error). Every response
|
|
will contain at least two keys: `msg` (a human-readable error message)
|
|
and `result`, which will be either `error` or `success` (this is
|
|
redundant with the HTTP status code, but is convenient when printing
|
|
responses while debugging).
|
|
|
|
For some common errors, Zulip provides a `code` attribute. Where
|
|
present, clients should check `code`, rather than `msg`, when looking
|
|
for specific error conditions, since the `msg` strings are
|
|
internationalized (e.g. the server will send the error message
|
|
translated into French if the user has a French locale).
|
|
|
|
Each endpoint documents its own unique errors; below, we document
|
|
errors common to many endpoints:
|
|
|
|
{generate_code_example|/rest-error-handling:post|fixture}
|
|
|
|
The `retry-after` paremeter in the response indicates how many seconds
|
|
the client must wait before making additional requests.
|
|
|
|
To help clients avoid exceeding rate limits, Zulip sets the following
|
|
HTTP headers in all API responses:
|
|
|
|
* `X-RateLimit-Remaining`: The number of additional requests of this
|
|
type that the client can send before exceeding its limit.
|
|
* `X-RateLimit-Limit`: The limit that would be applicable to a client
|
|
that had not made any recent requests of this type. This is useful
|
|
for designing a client's burst behavior so as to avoid ever reaching
|
|
a rate limit.
|
|
* `X-RateLimit-Reset`: The time at which the client will no longer
|
|
have any rate limits applied to it (and thus could do a burst of
|
|
`X-RateLimit-Limit` requests).
|
|
|
|
Zulip's rate limiting rules are configurable, and can vary by server
|
|
and over time. The default configuration currently limits:
|
|
|
|
* Every user is limited to 200 total API requests per minute.
|
|
* Separate, much lower limits for authentication/login attempts.
|
|
|
|
When the Zulip server has configured multiple rate limits that apply
|
|
to a given request, the values returned will be for the strictest
|
|
limit.
|
|
|
|
**Changes**: The `code` field in the response is new in Zulip 4.0
|
|
(feature level 36).
