The Inventory: Listing Your Channels

The /v2/channels endpoint acts as your personal registry. It returns a list of all channels that your Wawp instance interacts with, whether as a Creator (Owner) or a Follower (Subscriber).

📋 Understanding Channel Roles

The response includes a role field for each channel, which dictates your permissions.

1. OWNER

Definition: You created this channel.
Capabilities:
- Post updates (Text, Media, Polls).
- Change settings (Name, Picture, Description).
- Delete the channel.

2. ADMIN

Definition: You were promoted to admin by the Owner (Note: Admin promotion via API is currently limited).
Capabilities: similar to owner but usually cannot delete the channel.

3. SUBSCRIBER (GUEST)

Definition: You followed this channel from the directory.
Capabilities:
- Read messages.
- React with emojis.
- Mute/Unmute.
- Cannot post updates.

🛠️ Sync Strategies

The Startup Sync

When your application boots up, you should call this endpoint to populate your local state.

Fetch: Call GET /v2/channels.
Filter: Separate the list into "My Channels" (role=OWNER) and "Subscriptions" (role=SUBSCRIBER).
Display:
- Show "My Channels" in a "Broadcast Dashboard".
- Show "Subscriptions" in a "News Feed" view.

The "Stale Data" Problem

Channel metadata (like name or picture) changes rarely.

Optimization: Do not call this endpoint on every page load. Cache the result for 10-60 minutes.
Invalidation: If you perform a create or follow action, manually add that new item to your local cache instead of re-fetching the entire list.

🔍 Advanced Filtering

You can server-side filter the results to save bandwidth.

role=OWNER: Useful for "Creator Studios" where you only want to see channels you can post to.
role=SUBSCRIBER: Useful for "Reader Apps" where you only want to see content consumption sources.

⚠️ Common Pitfalls

Missing Channels: If you just followed a channel but it doesn't appear here immediately, give it 1-2 seconds. The sync between the WhatsApp server and the Wawp instance is asynchronous.
Duplicate Names: Remember that multiple channels can have the name "Test Channel". Always use the id (@newsletter) as the unique key in your UI.
