Vercel · Hosting and integrations
The Salesforce login, the WhatsApp token and the payment key sit in .env files and chat messages. When the developer leaves, so does the only copy. With Doppler, every key lives in one place and syncs to each Vercel environment. Secrets are write-only once saved. Databases, sign-in and monitoring come from the Vercel Marketplace and add their own keys.

The problem
What Doppler and integrations is
Facts from Vercel’s own pages, checked on 16 October 2026. The sources are at the end of this page.
How it works
Five steps. A key changes in one place and reaches the right environment, and nobody pastes it into a chat.

Step by step
Store
Keys stored once in Doppler
Salesforce, WhatsApp and payment keys live in one Doppler project, with a config per environment.
Sync
One sync per environment
Development, Preview and Production each get their own sync to the Vercel project.
Save
Secrets saved write-only
Keys land as Secret variables that nobody can read back. Public settings land as Config.
Add
Marketplace tools add their keys
A database, sign-in or monitoring tool connected from the Marketplace adds its own variables to the project.
Redeploy
Redeploy to apply
Changed values apply to new deployments only, so we redeploy after every change.
How it fits together
Doppler holds the keys. Vercel environment variables hand them to your app. Marketplace tools add their own. Salesforce has no Marketplace listing, so it connects through our code or Vercel Connect, where its connector is in Beta.

Use cases · worked examples
How Doppler and integrations fits into the work of the industries we serve, one step at a time.
Example 1 · Property management, Dubai · Infographic
Today: The tenant portal sends WhatsApp updates and logs requests in Salesforce. The only copy of the keys sat on a developer’s laptop, and he has left.
After: Every key moves into Doppler, with one sync for each Vercel environment. The WhatsApp token is changed in one place and the portal picks it up on the next deployment.
Worked example, step by step
The old keys are dead, the new ones live in one place, and nobody has a copy on a laptop.
Example 2 · Financial services, Mumbai · Infographic
Today: Preview builds and production share the same bank API key. One wrong test could move real money, and the key once showed up in a build log.
After: The team turns on separate production secret values. Previews run on test keys, every key is a write-only Secret, and long secret values are redacted in build logs.
Worked example, step by step
A preview can no longer reach a live bank account, and nobody can read the live key back.
Example 3 · Marketing agencies, Austin · Infographic
Today: Every campaign microsite needs a database, a sign-up form and error alerts. Each one means a new vendor account, a new card and keys pasted by hand.
After: The database and error monitoring come from the Vercel Marketplace. They add their own keys to the project and bill on the Vercel invoice. Leads still go to the client’s Salesforce through our code.
Worked example, step by step
A microsite with a database and alerts, and no new vendor account to open.

What Mindcat does
The assessment is free: a short read of the org and a written note. If you go ahead, the first build week is a fixed AED/SAR 14,900 (about USD 4,050), credited in full when you sign the build within 60 days. After go-live, we keep it patched, watched and changing every month.
