Motivation and Context

How did you test it?

1. Create merchant_account, api_key and mca (any connector)
2. Toggle dynamic routing

curl --location --request POST 'http://localhost:8080/account/merchant_1734609410/business_profile/pro_gPTjn9jLm0CxI8ZD1omL/dynamic_routing/success_based/toggle?enable=metrics' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: dev_K70Wr6zqJLbPECg8eEXrnZ43TW41JNUuXYHzRB50geiG0lViLExjxNUld6sgdNd0' \
--data ''

3. Create a payment

curl --location 'http://localhost:8080/payments' \
--header 'Content-Type: application/json' \
--header 'Accept: application/json' \
--header 'api-key: dev_K70Wr6zqJLbPECg8eEXrnZ43TW41JNUuXYHzRB50geiG0lViLExjxNUld6sgdNd0' \
--data '{
    "amount": 6540,
    "authentication_type": "no_three_ds",
    "confirm": true,
    "currency": "USD",
    "customer_acceptance": {
        "acceptance_type": "online"
    },
    "customer_id": "cus_uYakn3OQTUtAgetLDOE1",
    "payment_method": "card",
    "payment_method_data": {
        "card": {
            "card_cvc": "123",
            "card_exp_month": "10",
            "card_exp_year": "25",
            "card_holder_name": "joseph Doe",
            "card_number": "4242424242424242"
        }
    }
}'

Check the grafana dashboard with app = dynamo label in loki. Logs should have x-tenant-id and x-request-id in the headers.
