Use the following technique to send a file as a payload for an HTTP endpoint:
Step 1. Create a source connection. It can be any of the following connection types:
- Amazon S3
- Google Cloud Storage
- Microsoft Azure Storage
- Server Storage
- HTTP (web service)
- Google Sheets
- Google Analytics
- Inbound Email
Step 2. Create a destination HTTP connection.
Step 3. Create copy files flow. Use connection created in step 1 as the source and connection created in step 2 as the destination. Enter the file name to copy in the FROM field. The wildcard filenames are supported.
