Overview
The WhatsApp Multi-Session node allows users to interact with the WhatsApp Multi-Session API, specifically for managing contacts. The "Check" operation is used to verify if a specific phone number is registered on WhatsApp. This functionality is particularly useful for applications that need to validate user contact information before sending messages or engaging in communication. For example, businesses can use this node to ensure they are reaching out to valid WhatsApp users, thereby improving engagement rates and reducing unnecessary message failures.
Properties
| Name | Meaning |
|---|---|
| Session ID | The WhatsApp session ID required to authenticate the request. |
| Phone Number | The phone number to check, formatted with the country code but without the '+' sign. |
Output
The output of the "Check" operation will be a JSON object indicating whether the specified phone number is registered on WhatsApp. The structure typically includes fields such as:
success: A boolean indicating the success of the operation.exists: A boolean indicating whether the phone number is registered on WhatsApp.- Additional metadata may include error messages if applicable.
If the node can output binary data, it would generally relate to media files associated with other operations, not directly relevant to the "Check" operation.
Dependencies
- An API key credential is required to authenticate requests to the WhatsApp Multi-Session API.
- The node requires access to the WhatsApp Multi-Session server URL.
Troubleshooting
Common issues users might encounter include:
- Invalid Session ID: If the provided session ID does not exist or is incorrect, the node may return an error indicating that the session could not be found.
- Phone Number Format Error: Users must ensure that the phone number is correctly formatted (with country code, no '+'). Incorrect formatting may lead to validation errors.
- Authentication Errors: If the API key is invalid or expired, users will receive authentication-related error messages.
To resolve these issues, users should double-check their input values, ensure their API credentials are correct, and refer to the API documentation for proper formatting guidelines.
