Hello! I am trying to upload a PDF file from a webhook and send it to an API using “Multipart/form-data” body type. I am getting an error and am unsure why. I am very new to make so maybe i’m just not understanding it correctly. Any help is appreciated, thanks!

Hi @Parker_McKean

Welcome to community!

Please check the file data ({{1.file}}) format to confirm that it matches the data format accepted by the API call as it comes from the webhook.

@Parker_McKean

Please check if the data is in buffer format. If not, please download the file and map it to HTTP.
