Loops.so and attachments

I’m trying to send pdf attachments using loops.so

Loops.so requires the file to be bsae 64

Saving base 64 strings in the db, isn’t ideal - they’re huge.

Has anyone got this working?

Hi @mlewis2016,

When you have a file (in a file data type), you can reference it and then encode it in base64 when passing it to Loops through the API call you’re making

Example:

Hello,
I was asking myself this very question too. So far I have a workflow connected with Loops where I only send the pdf link, so the receiver can download it. However, it is not ideal in terms of user experience for the receiver.
I’m curious. How do you send it trough Loops? I use a data variable for the pdf link, can I reuse the same for the actual attachment?

How do you know @mlewis2016 that Loops.so requires the file to be bsae 64?

@jhonnatan.rangel, check out the Loops API documentation

@johnny thanks - this tip means I can remove some unnecessary parts to the implementation. I can get the API to fire from the connector when I initialise the call and I receive the email as expected with the attachment. Where I’m failing is getting it to fire from the front end, via API workflows - I’m getting an error that json is incorrect.

That’s a whole different thing, have you made sure your JSON is JSON safe using a tool like jsonlint

Thank you so much.
This was very useful, and I already made it work on my end. I share what I did for the workflow in case someone is in the same situation. I firts generated a pdf. I then send the email with the params I need to send, that includes the pdf encoded in base64.

This is the structure of the JSon. Ignore the dataVariables if that is not your case.

The filename value is the name of the pdf you want to give and the content is the type. I used “application/pdf” which is the MIME type of the file.

It works just fine. I hope it helps
