Despite the name, its not exactly a "bridge". It forwards messages from WhatsApp to Telegram and you can reply to them from Telegram.

Bugs and TODO

• Animated stickers are not supported from WhatsApp
• Document naming is messed up and not consistent on Telegram, have to find a way to always send sane names

PRs are welcome :)

Installation

• Make a supergroup with topics enabled

• Add your bot in the group, make it an admin with permissions to Manage topics

• Install git, gcc and golang on your system

• Clone this repository in $GOPATH/src

• Navigate into the cloned directory

• Run go build

• Copy sample_config.yaml to config.yaml and fill the values:

  • You can leave api_url in telegram section empty if you don't have any local Bot API server (recommended to have one for large files)
  • Uncomment one of the database sections according to your preferences
  • In the whatsapp section:
    • tag_all_allowed_groups: these are the groups in which others can use @all/@everyone to tag everyone. The values that you need to fill in this section can be found by sending /getwagroups to the bot after running it once. You have to fill in the value before @ character in the JID.
    • status_ignored_chats: these are the contacts (along with the country code) whose statuses will not be bridged to Telegram.

• Execute the binary by running ./watgbridge

• On first run, it will show QR code for logging into WhatsApp that can by scanned by the WhatsApp app in Linked devices

• It is recommended to restart the bot after every few hours becuase WhatsApp likes to disconnect a lot. So a Systemd service file has been provided. Edit the User and ExecStart according to your setup:

  • If you do not have local bot API server, remove tgbotapi.service from the After key in Unit section.
  • This service file will restart the bot every 24 hours
