Integrate API with custom connectors

(0) ShareShare
ReportReport
Posted on by

Hello,

I'm trying to integrate a basic and simple API, which works with HTTP form by POST request. The API is a sign provider which sign a PDF file I send, and return it signed (the field is "file".)

 

I will launch the action by the upload of a file in OneDrive Enterprise (the pdf which will be signed). Then, the new signed pdf that the API should return will be upload in OneDrive too.

But, I'm not sure about how to achieve the integration of the API, by custom connector. Could you confirm me it is possible ? I see all the good options in it (select POST etc) but I don't know what to put in Head and Content (I don't know much about json etc).

I got a 500 internal error when I try the custom connector, because I don't know what to put in the content.

There is just 1 field I want to exploit, the "file" I am supposed to tell in the flow after creating this custom connector.

 

The API documentation only gives the URL and the fact that form is encoded with mime-type ’application/multipart-form-data’.

Thx for your support,

    Hi @Florian34 ,

     

    You could achieve the integration of the API by custom connector, and could you please share more details about the error message?
