Hide salesforce api credentials in javascript client app
Keep Salesforce tokens off the browser
You should not store Salesforce credentials in JavaScript / HTML client code. Edge pipeline attaches Bearer tokens so static sites never embed secrets. RealComposer Secret Vault injects headers on Cloudflare Workers so only your edge URL is public.
Why Hide salesforce api credentials in javascript client app is hard without an edge proxy
Calling Salesforce directly from JavaScript / HTML risks leaked secrets, CORS blocks, or oversized JSON that slows rendering.
- Exposed API keys in JavaScript / HTML bundles or DevTools
- Sequential upstream calls on slow mobile networks
- Third-party rate limits and surprise billing spikes
How RealComposer Solves This at the Edge
Store credentials in Secret Vault
Save SALESFORCE_ACCESS_TOKEN in RealComposer.
Configure edge pipeline
Add upstream steps with vault header injection and map the response fields your client needs.
Call from JavaScript / HTML
Use your workspace edge URL with a restricted client token.
const res = await fetch('https://realcomposer.com/v1/workspace/hide-salesforce-credentials-javascript', {
headers: { Authorization: 'Bearer rc_live_client_token' }
});
const data = await res.json();
{
"status": 200,
"debug_trace": "trace_batch2",
"data": {
"id": "obj_batch2",
"status": "active",
"audit_logs": [

}

}
}
curl -X GET "https://realcomposer.com/v1/workspace/hide-salesforce-credentials-javascript" \ -H "Authorization: Bearer rc_live_client_token"
Developer Questions & Troubleshooting
Is it safe to call Salesforce from JavaScript / HTML?
Only if secrets stay off the device. RealComposer injects credentials on the server edge so clients never hold production keys.
Does RealComposer add latency?
Cloudflare edge execution adds a few milliseconds; caching can answer repeat calls in under 10ms.
