MMG Payment Integration in Guyana
Revamped GY supports MMG payment integration for approved Guyana merchants, including WooCommerce checkout, sandbox configuration, transaction verification, recovery tools and a documented production handover.
Built for an agreed operational scope
Connect payment status to the order your team must fulfil
An MMG integration connects a merchant’s approved payment service to a website or business workflow. For WooCommerce, the customer selects MMG, continues through the hosted payment flow and returns to the store. The order must then reflect the verified transaction state rather than an untrusted browser message.
Revamped GY can configure and test the MMG Checkout for WooCommerce plugin or scope a different approved integration where the merchant requirements justify it. The work includes callback and return URLs, credential handling, status mapping, logs and staff recovery tools.
MMG controls merchant onboarding, credentials and production approval. Revamped GY cannot create an MMG merchant account, issue credentials or bypass the provider’s acceptance process. The merchant remains responsible for its agreement, customer policies and financial reconciliation.
MMG integration scope
Merchant readiness review
Confirm the approved merchant account, environment, currency, callback requirements and people responsible for testing.
Credential import and protection
Configure the supplied sandbox or live package without exposing private keys in content, screenshots, logs or support files.
WooCommerce checkout
Enable MMG for the agreed checkout type and preserve product totals, order records and customer return behaviour.
Verification and recovery
Provide tools for delayed returns, pending orders and controlled transaction verification using the provider response.
Reporting and diagnostics
Support reconciliation with order notes, payment identifiers, filtered exports and diagnostics that exclude secrets.
Launch evidence and handover
Record test outcomes, production configuration, staff tasks, support boundaries and the rollback plan.
A controlled path from sandbox to production
Confirm merchant access
Review the account, MMG requirements, website URL, currency and supplied sandbox credential package.
Configure sandbox
Install or configure the approved integration, callback URL, return handling and safe diagnostic logging.
Test complete transaction states
Exercise success, cancellation, refusal, interrupted return, delayed update and controlled verification paths.
Submit required evidence
Prepare the evidence requested by MMG and wait for the merchant’s live credential package and approval.
Controlled live activation
Import live credentials, confirm the public callback and run only the production check authorised by the merchant.
Payment integration controls
Payment code has a narrow trust boundary. The website must verify the provider response, protect credentials and avoid marking an order paid because a customer reached a return URL. Logs must support diagnosis without recording private keys or unnecessary personal information.
- Separate sandbox and production credentials
- HTTPS callback and return URLs
- Provider-side transaction verification
- No card data stored by the website
- No cache on checkout or callbacks
- Explicit pending, failed and paid order states
- Restricted diagnostics and support exports
- Reconciliation and staff recovery procedures

These answers define the public service boundary. The proposal records the exact project scope.
Can Revamped GY open an MMG merchant account for me?
No. Merchant onboarding, approval and credentials are controlled by MMG. Revamped GY can help prepare the website integration and technical evidence after the merchant has the required access.
Does the integration support WooCommerce Blocks Checkout?
The current Revamped GY MMG Checkout product states support for WooCommerce Blocks and classic checkout. Compatibility is confirmed against the store versions and test environment during the project.
Can the integration be tested without charging a customer?
Sandbox testing is the normal first stage when MMG supplies UAT credentials. Live financial testing requires the merchant’s explicit approval and production credentials.
What happens if the customer closes the browser after payment?
The integration should retain a pending order and provide a controlled way to verify the transaction with MMG. The exact recovery flow depends on the installed version and provider response.
Does Revamped GY guarantee MMG approval or payment success?
No. Approval is controlled by MMG and transaction outcomes depend on the provider, customer account, network and merchant configuration. Revamped GY is responsible for the agreed website integration and evidence.
Prepare the merchant access before development starts
