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. If you are using a supported crash reporting library, please use their preferred submission mechanisms.
Ensure submission token exists
First step is to ensure you have a submission token created. Learn more about submission tokens in the product guide.
Ensure listener exists
Next step is to ensure that a listener exists for submitting crash data. Look for listeners with the
http/writerlabel. Listener settings are found under the
Configuration Organization menu item.
In the above example, if the server is hosted at
testing.company.com, then we are able to submit dump files to either http://testing.company.com:6097/post or https://testing.company.com:6098/post. These are the first two entries in the above screenshot, with the
Note on curl usage
For large files, include the header flag
-H "Expect:" to override some default
curl behavior which can cause issues when uploading to Backtrace. The examples below include this flag.
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 -v --data-binary @example_minidump.dmp -H "Expect:" "https://testing.company.com:6098/post?format=minidump&token=7e7f38ea321471dfdf76adad1bd101c4ec1010dd6eee113d347f6137179ed9c3"
format parameters are required in order for the dump to be submitted.
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
curl -v --data-binary @example_minidump.dmp -H "Expect:" "https://testing.company.com:6098/post?format=minidump&token=7e7f38ea321471dfdf76adad1bd101c4ec1010dd6eee113d347f6137179ed9c3&version=1.0"
For more information on attributes, see the product guide.
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
curl -v -F "upload_file=@example_minidump.dmp" -H "Expect:" -F "firstname.lastname@example.org; type=application/json" "https://testing.company.com:6098/post?format=minidump&token=7e7f38ea321471dfdf76adad1bd101c4ec1010dd6eee113d347f6137179ed9c3"
Alternatively, attachments can be submitted afterwards using standard POST, in this case to object 5:
curl -v --data-binary @config.json -H "Expect:" -H "Content-Type:application/json" "https://testing.company.com:6098/post?token=7e7f38ea321471dfdf76adad1bd101c4ec1010dd6eee113d347f6137179ed9c3object=5&attachment_name=config.json"
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.
It is also possible to use the https://submit.backtrace.io receive layer to submit dumps. This is preferred to use over port 6098 for better quality of service. This is only an option for hosted customers. For on-premise, it is possible to customize listeners.
The POST URL is in the following format:
The following CURL command is used:
curl -v --data-binary @file.dmp -H "Expect:" "
