The Template that will be used to send the email.

The email address to use for as the sender.

The template model values to be combined with the template you selected during sending.

The main recipient addresses for the email that will be sent. This field is optional, but at least one To, Cc, or Bcc email address must be specified in order to send an email with Postmark.

Additional email addresses that should be CC'd when sending the email. This field is optional, but at least one To, Cc, or Bcc email address must be specified in order to send an email with Postmark.

Additional email addresses that should be BCC'd when sending the email. This field is optional, but at least one To, Cc, or Bcc email address must be specified in order to send an email with Postmark.

Set message stream ID that's used for sending. If not provided, message will default to the "outbound" transactional stream.

The HTTP method we'll use to perform the request.

Any URL with a querystring will be re-encoded properly.

If yes, request data below will be overridden with the raw data from the previous step (you are still responsible for headers though, like Content-Type). Defaults to no.

Place raw data for the request here. Could be JSON, XML, etc. Nothing is parsed for you here (including extra line breaks or spaces -- everything is sent verbatim). You probably need to define a header below corresponding to your data Content-Type. Reminder: data provided in this field is completely ignored if you chose "yes" to pass-through.

By default we convert fields with double underscores into nested dictionaries. Select no here to turn this behavior off.

A pipe (|) separated username, password combo for standard HTTP authentication.

Key, value pairs to be added as headers in all requests.

This is the email From address that you will send en email From. It should match one of your Sender Signatures that are verified in the Postmark Dashboard.

This is the recipient(s) of the email message. This field is optional, but at least one To, Cc, or Bcc email address must be specified in order to send an email with Postmark.

Additional email addresses that should be CC'd when sending the email. This field is optional, but at least one To, Cc, or Bcc email address must be specified in order to send an email with Postmark.

Additional addresses that should be BCC'd when sending the email. This field is optional, but at least one To, Cc, or Bcc email address must be specified in order to send an email with Postmark.

This is the subject of the email you'd like to send.

This is the plain text portion of your email. You may include both a text and HTML part, but at least one or the other is required to send email via Postmark.

This is the HTML portion of your email. You may include both a text and HTML part, but at least one or the other is required to send email via Postmark.

Set message stream ID that's used for sending. If not provided, message will default to the "outbound" transactional stream.

This should return a list of dictionaries of content type JSON in reverse chronological order. For example: [{"id":1234},{"id":1235}]

If the returned JSON is not a list and is instead an object (maybe paginated), enter the key that contains the results. Example: "results", "items", "objects", etc... (children via dot syntax supported)

Zapier deduplicates the array we see each poll against the id key. If the id key does not exist, you should specify an alternative unique key to deduplicate off of. If neither are supplied, we fallback to looking for the shortest key with id in it otherwise we will raise an error.

If the content fetched is XML or HTML, optionally define an xpath to extract data from the content. Will trigger whenever the content at the xpath changes!

By default, Zapier gives you the entire payload of the webhook. If this is specified, Zapier will only grab the child key from the object(s) sent to Zapier. For example, given {"contact": {"name": "Mike"}}, add "contact" here to only return {"name": "Mike"}. Traverse more deeply nested children by using dot-separated syntax. Line item payloads will run your Zap for each instance of the child key.

We recommend not putting any query string arguments in the URL (use "Query String Params" below).

These params will be URL-encoded and appended to the URL when making the request. Note: If you specify nothing for this field, we will automatically encode and include every field from the previous step in the query string. If you don't want this, use the "Custom Request" action.

If "yes", this dumps the results directly to a key (set below) as JSON. If "no", we simulate a form.

Only used if As JSON.
