Creating a Funding Channel

A Funding Channel is a configuration of a card Funding Type for an Immersve card issuing partner. See Funding Protocols for information on how to choose a Funding Type.

Your Funding Channel ID must be referenced when creating cardholder Funding Sources. A Funding Source is required for each combination of network and token that you wish to support for your card issuing.

The steps to create a Funding Channel depend on which funding protocol is selected.

Universal EVM

See Universal EVM Funding Protocol for more information on this protocol and how to deploy a Funds Storage contract.

Funding Channel creation requires the prior deployment of a Funding Storage Contract. By creating a Funding Channel the contract is registered with Immersve. This will ensure deposits to the contract are scoped to your application.

Set up environment variables:

  account_admin_api_key="<your_account_admin_api_key>"
  account_admin_api_secret="<your_account_admin_api_secret>"
  partner_account_id="<your_partner_account_id>"
  funds_storage_address="<your_storage_address>"
  funding_type_name="polygon-amoy-usdc-universal-evm-test"

Create a funding channel:

  funding_channel_id=$(curl -X POST "https://test.immersve.com/api/funding-channels" \
    -H "Content-Type: application/json" \
    -H "x-api-key: ${account_admin_api_key}" \
    -H "x-api-secret: ${account_admin_api_secret}" \
    --data '{
      "accountId": "'${partner_account_id}'",
      "fundingTypeName": "'${funding_type_name}'",
      "params": {
        "storageAddress": "'${funds_storage_address}'"
      }
  }' | jq -r .id)
