Overview
This node interacts with the WaAPI API to retrieve information about channels. Specifically, the "Get Channels" operation fetches details of a channel instance by its unique identifier. This is useful in scenarios where you need to programmatically access channel data from the WaAPI service, such as integrating channel information into workflows, monitoring channel status, or automating channel management tasks.
Practical examples include:
- Fetching channel details to display in a dashboard.
- Using channel data to trigger other workflow actions based on channel properties.
- Synchronizing channel information with other systems.
Properties
| Name | Meaning |
|---|---|
| Id | The unique numeric identifier of the channel instance to retrieve. This is required to specify which channel's information should be fetched. |
Output
The node outputs JSON data representing the channel details retrieved from the WaAPI API. The structure typically includes all relevant fields describing the channel instance, such as its ID, name, status, and any other metadata provided by the API.
If the API supports binary data for channels (e.g., images or files associated with a channel), the node would output this in a binary format; however, based on the provided code and operation, the output is primarily JSON data.
Dependencies
- Requires an active connection to the WaAPI API service.
- Needs an API authentication token or key configured in the node credentials to authorize requests.
- The base URL for API requests is
https://waapi.app/api/v1. - The node uses standard HTTP headers for JSON content negotiation.
Troubleshooting
- Missing or invalid Id: Since the Id property is required, omitting it or providing an invalid value will cause errors. Ensure the Id is a valid number corresponding to an existing channel.
- Authentication errors: If the API key or token is missing, expired, or incorrect, the node will fail to authenticate. Verify that the API credentials are correctly set up.
- Network issues: Connectivity problems to the WaAPI endpoint can cause request failures. Check network access and proxy settings if applicable.
- API rate limits or quota exceeded: The WaAPI service may limit the number of requests. If rate limits are hit, wait or adjust usage accordingly.
