An Account Management System (AMS) connector for Fineract. This connector gets invoked after a collection has been made on a Fineract client's M-PESA wallet. Its primary role is to notify the Fineract service about a successful payment made by a client.
This AMS connector is a Zeebe project that is part of the OAF Payment Hub EE setup. See the Payment Hub EE documentation for more information about Zeebe projects and Payment Hub in general.

Clone the project
git clone https://github.com/one-acre-fund/ph-ee-connector-ams-fineract.git
cd ph-ee-connector-ams-fineract
This connector is expected to be run alongside other connectors/services. It depends on some of
those services being up
and healthy. For local development, the services that are most critical for running this project
have been included in
the docker-compose.yml
file. The following components are included:
- Zeebe: A workflow engine for microservices orchestration. This must be running in a healthy state otherwise errors will occur when the services below attempt to connect to it.
- Zeebe-ops: Provides APIs for carrying out certain operations on zeebe such as uploading a bpmn file
- Channel-connector: Provides APIs for initiating collection requests
- Mpesa-connector: Contains workers that handle the connection to M-PESA for making the actual collection from a client's wallet
A lot more services can be added to the above based on your needs, but to run the Fineract ams
connector locally,
the ones listed above are the required minimum.
Please note that the docker-compose.yml
file in this repository should NOT be used in a production
environment.
Some images listed in the docker-compose.yml
are available on OAF's Azure Container Registry (
ACR). To be able to pull
them, certain permissions must be granted to your azure account. Follow the steps below to
successfully run the project:
-
Ensure Docker is installed on your machine
-
Authenticate with azure. Install the Azure CLI on your machine if it's not already available, and then run the command below
az acr login -n oaftech # Log in to OAF's ACR through the Docker CLI.
-
Run the project:
Update
src/main/resources/application.yml
with the appropriate values where necessary, or provide the values as environment variables in theservices.fineract-connector.environment
section of thedocker-compose.yml
file, and run the command below:docker compose up -d
To initiate a collection request, and have the Fineract connector notify the Fineract AMS about the payment, follow the steps below:
-
Upload the Fineract bpmn (found in
src/main/resources/mpesa_flow_fineract-oaf.bpmn
) through * zeebe-ops* by sending a POST request tohttp://localhost:5001/zeebe/upload
with the file attached. -
Send a collection request through the channel-connector by sending a POST request to
http://localhost:5002/channel/collection
with a sample body as shown below:{ "payer": [ { "key": "MSISDN", "value": "254113888031" }, { "key": "fineractAccountID", "value": "60649568" } ], "amount": { "amount": "1", "currency": "KES" }, "transactionType": { "scenario": "MPESA", "subScenario": "BUYGOODS", "initiator": "PAYEE", "initiatorType": "BUSINESS" } }
-
Check the logs in the fineract-connector container to see that settlement has been handled, and see the result of calling the Fineract service
If an error occurs while carrying out any of the steps above, check if the zeebe container is in a
healthy state by
either viewing its state through docker ps
or sending a GET request
to http://localhost:9600/health
.
If the zeebe container shows state as unhealthy or the health endpoint doesn't return a 204 status
response, restart the
zeebe container.
