Fax From Zoho — Using Zoho Flow, Deluge, or a Webhook to Our API

How it works

Pick the Zoho tool that matches where your data lives. Zoho Flow can listen for a CRM or Books event and run a Webhook action that POSTs to /v1/faxes. Inside Zoho CRM or Creator, a Deluge custom function can build the request with invokeUrl, reading the recipient number and a document URL from the record and sending them with your key. Books and Invoice can export a document to a URL you then pass as document_url so our server fetches it. Whichever route you use, the response returns a fax id you write back onto the Zoho record, and a registered webhook endpoint can update that record when the fax is delivered.

What you can do

• ✓Fax a Zoho CRM, Books, or Creator record when your automation fires
• ✓Use Zoho Flow's Webhook action or a Deluge invokeUrl call to reach /v1/faxes
• ✓Pass an exported document URL so the file is fetched, not encoded
• ✓Write the returned fax id back onto the Zoho record for tracking
• ✓Register a webhook so fax.delivered updates the record automatically
• ✓Store the key in a Zoho connection instead of visible record fields

Setup steps

1. 1Put the account on Business or Enterprise and create a key at /dashboard/developers
2. 2Choose Zoho Flow for cross-app logic or Deluge for in-app scripting
3. 3Build the trigger — a CRM stage change, a new invoice, or a form submission
4. 4Add a Webhook action or invokeUrl call that POSTs to /v1/faxes
5. 5Read the recipient and a document URL from the record into the request
6. 6Write the fax id back onto the record and register a webhook for status

Example

// Zoho Deluge custom function
response = invokeUrl
[
  url: "https://www.sendfaxmail.com/v1/faxes"
  type: POST
  headers: { "Authorization": "Bearer sfm_live_xxxxxxxx" }
  parameters: {"to": faxNumber, "document_url": docUrl}.toString()
];
faxId = response.get("id");
