Mailchimp and hubspot combined cache layer
Internal dashboards with one cached audience view
To mailchimp and hubspot combined cache layer, put a TTL cache on your RealComposer pipeline. Compose and cache merged marketing audience JSON. Shared edge cache absorbs repeat traffic before it reaches Mailchimp and HubSpot.
Why Mailchimp and hubspot combined cache layer is hard without an edge proxy
Calling Mailchimp and HubSpot directly from Retool risks leaked secrets, CORS blocks, or oversized JSON that slows rendering.
- Exposed API keys in Retool 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 MAILCHIMP_API_KEY, HUBSPOT_ACCESS_TOKEN in RealComposer.
Configure edge pipeline
Add upstream steps with vault header injection and map the response fields your client needs.
Call from Retool
Use your workspace edge URL with a restricted client token.
const res = await fetch('https://realcomposer.com/v1/workspace/mailchimp-hubspot-shared-edge-cache', {
headers: { Authorization: 'Bearer rc_live_client_token' }
});
const data = await res.json();

Developer Questions & Troubleshooting
Is it safe to call Mailchimp from Retool?
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.
