Webhook not triggering with large base64 data

[EnigmaXXIII]

Hi,

I’m trying to send large (c.38mb) base64 encoded data to a webhook trigger. Each time I do nothing seems to happen. I don’t see any executions, fails, attempts, or anything. However, when I reduce the payload to around 5mb, everything works fine.

Am I hitting limits?

Thanks.

Hey @EnigmaXXIII,

Quick question: How are you sending the data? Is it via a URL? According to Stack Overflow, URLs have a limit of approximately 2000 characters.
Could you try sending it in the body using the POST method instead?

Hey @Shirobachi,

I am sending as a body request already. Here’s an example output that works when using a smaller file. Only change is file size…
