Asynchronous file conversions are made by setting parameter Async to True. The response of the asynchronous conversion contains JobId which could be used to poll the result. The ConvertAPI support two types of asynchronous result - Polling and WebHooks.

Polling

Asynchronous conversion request

[POST]
https://v2.convertapi.com/convert/docx/to/pdf?Secret=XXX&Async=true&File=http://example.com/myfile.docx

Response

{"JobId": "d3bd2056-4330-4cf3-9b18-483a2412dd6b"}

Now using JobId it is possible to retrieve finished conversion result or get the conversion status.

Poll result request

[GET]
https://v2.convertapi.com/job/d3bd2056-4330-4cf3-9b18-483a2412dd6b

Only one request of pulling is accepted, no concurrent poll requests are allowed. The second pool request will get 503 status code if first is not finished. Also there is delay of 5 second for the seconds pool request.

Response HTTP status codes

  • 200 Conversion is successful. Response is a conversion result.
  • 202 Conversion in progress.
  • 404 JobId is invalid or response is expired.
  • 503 No concurrent poll requests are allowed.
  • 5XX Conversion error. Response is an error message.

WebHooks

The ConvertAPI support WebHooks, when conversion is done the WebHook URL is called with JobId. The conversion request should include WebHook parameter with URL which should be called.

Asynchronous conversion request

[POST]
https://v2.convertapi.com/convert/docx/to/pdf?Secret=XXX&Async=true&WebHook=http://www.example.com/WaitingForWebHook&File=http://example.com/myfile.docx

Response

{"JobId": "d3bd2056-4330-4cf3-9b18-483a2412dd6b"}

The response includes JobId and when conversion is finished the WebHook URL will be called with the same JobId using GET method:

http://www.example.com/WaitingForWebHook?JobId=d3bd2056-4330-4cf3-9b18-483a2412dd6b

Using received JobId the actual conversion result could be read.

Poll result request

[GET]
https://v2.convertapi.com/job/d3bd2056-4330-4cf3-9b18-483a2412dd6b

Only one request of pulling is accepted, no concurrent poll requests are allowed. The second pool request will get 503 status code if first is not finished. Also there is delay of 5 second for the seconds pool request.

Response HTTP status codes

  • 200 Conversion is successful. Response is a conversion result.
  • 202 Conversion in progress.
  • 404 JobId is invalid or response is expired.
  • 503 No concurrent poll requests are allowed..
  • 5XX Conversion error. Response is an error message.

Semi-Asynchronous

Semi-Asynchronous file conversions are useful when connection to ConvertAPI is lost during large file conversion. To avoid repetitive conversion, provide JobId parameter with self generated UUID (RFC 4122).

Semi-Asynchronous conversion request

[POST]
https://v2.convertapi.com/convert/docx/to/pdf?Secret=XXX&JobId=d3bd2056-4330-4cf3-9b18-483a2412dd6b&File=http://example.com/myfile.docx

In case of disrupted connection treat this conversion as if it was asynchronous conversion. Retrieve conversion result like described in asynchronous conversion section.

Delete job

If job is no longer required it can be deleted using DELETE request or it would be automatically deleted after maximum two hours.

Delete job request

[DELETE]
https://v2.convertapi.com/job/d3bd2056-4330-4cf3-9b18-483a2412dd6b

Response HTTP status codes

  • 200 Deleted successful.
  • 404 JobId is invalid or already deleted.
  • 5XX Delete error. Response is an error message.
