Do I need to keep my phone ON for this integration to work?

Yes. You will need the device where WhatsApp is installed to remain connected to the internet for the integration to work, functioning similarly to WhatsApp Web. If the device is disconnected, the messages received while inaccessible won't be available on the YesHello platform.

Can I have WhatsApp open in a web browser at the same time?

No. If you open WhatsApp on a web browser the connection with Chat API will be interrupted and you will have to go back to your Chat API account and reconnect it by scanning the code once again.

Are there any limits or charges associated with Chat API?

Chat API provides a free 3 days trial which you can use to test the integration. After that, a paid subscription will be necessary. The current price for Chat API is $39 and includes 6,000 messages per day. Note that the Chat API prices are excluded from the YesHello subscription.

Can I used WhatsApp Web & Chat API at the same time?

Troubleshooting The Chat API Integration

The Chat API WhatsApp integration relies on receiving WhatsApp messages from your mobile phone and passing them to YesHello. Since this process is reliant on a mobile phone which may be on the move and may not have have a consistent internet connection, there may be some troubleshooting required.

If No Messages Are Being Passed

If no messages are being passed to YesHello you should check the following items:
If messages are arriving in YesHello delayed, you should check the following items:
Pro Tip:
Works of an instance depends directly on the connected phone. If the phone has an unstable Internet connection, the API will process messages with a delay.
In addition, it often happens that when the screen is locked, the phone works in the background, this also slows down the API. To ensure faster connection, please make sure your phone does not have these problems

Mobile Phone Is On And Connected To The Internet

This may seem simple, but there are several situations where a mobile phone may seem to be connected to the internet when it is not. For example, you may be connected to Wifi, but the Wifi is not connected to the internet. Use Speedtest to ensure you have a strong and stable internet connection.
Something more difficult to check is if the internet connection is stable. Generally, to ensure you have a stable connection, you will want to have a dedicated phone that is always connected to a stable Wifi. Using a personal phone that you carry around will reduce your reliability.

Chat API Is Successfully Connected To The Phone

When your phone is successfully connected to the Chat API dashboard you will see this banner.
If this message is not shown, it may be that you have WhatsApp Web open in another location. If this is the case, you may connect your WhatsApp to Chat API once again by scanning the QR code & refrain from using WhatsApp Web in other places. Remember WhatsApp Web cannot be used while you are using Chat API.

Check That Webhook Is Present In The Chat API Dashboard

Chat API uses a webhook as part of their integration with YesHello. When connecting to Chat API in YesHello settings this automatically added to Chat API.
If the webhook is not present in your Chat API dashboard, please add webhook URL below.
