Quick start

1
Add the chat to your website

In your Subcontext dashboard, open Agents, your agent, Channels, Web. Switch it on and paste the snippet before </body> on your pages:
html
```
<script
  id="webchat-embed-script"
  src="https://js.subcontext.com/webchat-latest.js"
  data-agent-id="YOUR_AGENT_ID"></script>
```

Get an access token for your server

Create an API application under Integrations, API applications, then exchange its client id and secret for a token that lasts two hours:

curl -X POST https://subcontext.com/oauth/token \
  -d grant_type=client_credentials \
  -d client_id=YOUR_CLIENT_ID \
  -d client_secret=YOUR_CLIENT_SECRET \
  -d scope=read \
  -d resource=https://subcontext.com/api/v1

Call the API

Send the token in the Authorization header. This lists your products:

curl https://subcontext.com/api/v1/products \
  -H "Authorization: Bearer YOUR_ACCESS_TOKEN"
