HTTP Submission of dumps

Perhaps you are have a pre-existing crash reporting facility or are generating dump files using MiniDumpWriteDump on Windows, this guide shows you how to submit these over HTTP or HTTPS.

Ensure submission token exists

First step is to ensure you have a submission token created.

Ensure listener exists

Next step is to ensure that a listener exists for submitting crash data. Look for listeners with the http/writer label. Listener settings are found under the Configuration Organization menu item.

In the above example, if the server is hosted at, then we are able to submit dump files to either or These are the first two entries in the above screenshot, with the http/writer labels.

Submit a dump file

For this example, let us assume that our submission token is 7e7f38ea321471dfdf76adad1bd101c4ec1010dd6eee113d347f6137179ed9c3 and that the http/writer end-point is

An HTTP POST is used to submit a dump file. See below for an example curl invocation.

curl -v --data-binary @example_minidump.dmp ''

Both the token and format parameters are required in order for the dump to be submitted.

Attaching Attributes

User-defined attributes can also be passed as additional query string parameters. For example, let's say that we wanted to submit a minidump and set the version attribute associated with it to 1.0.

curl -v --data-binary @example_minidump.dmp ''

For more information on attributes, see: Attributes

Attaching Files

User-supplied files can be passed in multipart post requests. The multipart form must begin with the minidump, and any attachment parts must have a name starting with "attachment_" and ending in the desired name of the attachment. For example, say we want to attach a configuration JSON named config.json:

curl -v -F "upload_file=@example_minidump.dmp" -F "attachment_config.json=@config.json; type=application/json" ''

Alternatively, attachments can be submitted afterwards using standard POST, in this case to object 5:

curl -v --data-binary @config.json -H "Content-Type:application/json" ''

Note that curl requires explicitly specifying the Content-Type for attachments, as demonstrated, but a custom client can omit this parameter. In this case, the server will automatically determine the Content-Type based on the attachment's name.
