Hello @Clicknamics ,

Thank you for sharing the workflow details and granting consent to access your account.

We’ve checked the workflow and the API request sent to iTexMo. The error “Message encoding format is invalid” is occurring due to unsupported characters in the Message field.

The iTexMo SMS API only supports plain GSM / ASCII text. Your message contains special (Unicode) characters, for example:

• Smart apostrophe: Here’s
• Special punctuation or formatting from copied text
• Certain symbols in long URLs

These characters cause the API to reject the message with an encoding error.
Please update the Message field by:

1. Removing smart quotes and special characters
   • Change Here’s → Here is
2. Use only plain English letters, numbers, and basic punctuation
3. Avoid emojis or special symbols
4. (Optional) Shorten or remove the URL temporarily to test

Once the message is converted to plain text, the workflow should execute successfully without the encoding error.

Please try this and let us know if you need further assistance—we’ll be happy to help.

hi @Hrishabh.pabbly after removing the apostrophe, some workflow works and the others don't like this one
