How do I add journey and device details to a Webhook request, and check what was sent?

Besides the Device, Tag, and Event macros from the DATA BUILDER panel, you can type these placeholders directly into the URL, HEADERS, or DATA section of a Webhook step:

• {{application_code}}, {{traveler:id}}, {{event:name}}
• {{journey:uuid}}, {{journey:name}}, {{point:uuid}}, {{point:name}}
• {{device:platform}} (for example Android or iOS), {{device:push_subscribed}} (true or false)
• {{now}} (ISO 8601, UTC), {{now:unix_ms}}
• {{tags:all}}: all tag values as one JSON object. Use it unquoted, for example "user_properties": {{tags:all}}.

A placeholder inside quotes always becomes a string. Unquoted, it keeps its type (number, boolean, or array), but it must be the field's entire value. A misspelled or unknown placeholder is sent exactly as typed, with no error.

To check what was sent, open the Calls log tab in the step's drawer. It shows time, user, result, and duration for the last 30 days. Filter by Success, HTTP error, or No response, or search by exact User ID or HWID. Expand a row to see the request and the response or error text.

• Bodies over 4 KB are cut and marked …[truncated].
• Header values such as tokens are replaced with [redacted].
• Users dropped before the request was sent, for example by a rate limit, don't get a row.
