> Credit transfers to your Customers can be recorded within Mangrove to keep your inventory up to date.

Within each Customer order, find the right delivery, and **Transfer** the credits.

  <Tab title="Puro CORCs">
    Puro CORCs can be transferred directly through Mangrove to customer’s Puro accounts through a Mangrove integration with MyPuro.

    <Note>
      Ensure that your Mangrove account has your API Key credentials configured. Speak to the Mangrove team if you are unsure whether this is configured!
    </Note>

    <Steps>
      <Step title="Ensure that the Puro issuance has its existing **Registry Issuance Details** recorded">
        * The Project’s **External Registry Account Number** is set on **Project > Project Details > Registry Details** section
        * The CORC Bundle number should be set on the issuance’s **Registry External ID**
      </Step>

      <Step title="Ensure that you have your Customer’s Puro registry account number recorded">
        * Request the Customer’s Puro registry account number (they will have to get that from their MyPuro portal)
        * Within the **Customer**, add their Puro registry account under the **Registry Accounts** section
      </Step>

      <Step title="In the Customer order, select the particular delivery you need to complete" />

      <Step title="Transfer the delivery">
        * If the credits are from a Puro project, a transfer form will collect the necessary details to complete the transfer directly within Puro
        * Select the Customer’s **Registry Account** that the credits are to be transferred to
        * Confirm any additional notes, the Unit Price and Currency of the credits being transferred, and add a **Beneficiary Contact Email** which will receive an email confirmation from Puro when the transfer has been completed.
        * Once the transfer is complete, the transaction ID will be visible on the credit Delivery
      </Step>

  <Tab title="CSI C-Sinks">
    CSI credits can currently only be transferred through the Global C-Sink Tool in the CSI EasyCERT portal. We are working with CSI on activating a more direct transfer mechanism.
