Overview

Portal integrates with Meld so you can offer buy, sell, and transfer crypto experiences via Meld’s White-Label API — an aggregated network of fiat-on/off-ramp providers exposed as a single embeddable session. This page covers one-time setup in the Portal Dashboard and links to the White-Label API workflow guide.

​
Steps to enable the Portal Meld integration

​
1. Create your Meld credentials

  • Sign up for a Meld account at dashboard.meld.io.
  • From the Meld Dashboard, generate API keys for the environments you plan to use (sandbox and production are issued separately).
Keep your Meld API keys secure. You will configure them in Portal in the next step.

​
2. Enable the Meld integration in Portal

  1. Open the Portal Dashboard.
  2. Navigate to the Integrations page.
  3. Locate Meld and configure your integration.
  4. Paste your Meld API key for the selected Portal environment.
  5. Save.

Integrations are environment-scoped. Configure Meld separately for each environment (for example Development and Production), using the matching Meld sandbox or production API key.

​
3. Configure webhooks (optional)

Webhooks are configured directly in Meld Dashboard. See Webhooks.

​
Supported countries, currencies, and assets

Meld’s coverage spans dozens of countries, fiat currencies, crypto assets, and chains, and the catalog evolves with provider availability. Rather than hard-coding a list, query the discovery endpoints at runtime to populate dropdowns and validate selections:
  • Countries — GET /clients/me/integrations/meld/discovery/countries
  • Fiat currencies — GET /clients/me/integrations/meld/discovery/fiat-currencies
  • Crypto currencies — GET /clients/me/integrations/meld/discovery/crypto-currencies
  • Payment methods — GET /clients/me/integrations/meld/discovery/payment-methods
  • Service providers — GET /clients/me/integrations/meld/discovery/service-providers
See the White-Label API guide for end-to-end discovery examples.

Cache the discovery responses client-side — countries, currencies, and payment methods change rarely and re-querying on every page load adds unnecessary latency.
