We have requirement to convert Appian document to Base64 string and pass it as a parameter in the JSON to a Integration call.
Could someone suggest a best way to do this with any plugins?
Appian version we use : 18.2
Discussion posts and replies are publicly visible
Sending Base64 in JSON is supported in Appian 18.3 +
Thanks Danny. But is there an alternate approach to do this in 18.2
How do you integrate this directly into the Web API object? I have a client trying to access single documents from SAP via an API endpoint I've set up, and regardless of how I try to format the http response, it just passes back either binary data or just the plain document id.
Do these docs help? https://docs.appian.com/suite/help/20.2/passing-a-web-api-document-into-a-process-model.html
I don't see any mention of Base64 there(?). The remote team is asking to retrieve base64 instead of binary, if possible.
To clarify: I have an API set up where the remote team is passing in a document type and a primary key id. Logic on our end attempts to retrieve a matching document from the Appian filesystem, and when a match is found, we send it back in the response. Currently this is going over as binary data, but they're asking if we can convert it to a Base64 string first - and I'm not finding any way to do so (and if it already is, for example, I'm not seeing any way to verify or troubleshoot).
Thanks, Danny. This was helpful. Can we just receive only document at a time or a combination of document or other data types possible?
You can only receive only document at a time via the request body but you can also send other data type data as query parameters
Hi Mike, Do you have any solution for the above scenario? I am trying to implement something similar.
Hi Shikha, I'm not sure I ever got an answer to my last inquiry from months ago - maybe Danny Verb can provide some additional input?
The best solution would be to upgrade Appian Versions since in 18.3 you can easily send and receive base64 documents.
