This account provides a **CodigoFabricante** and is tied to an **email address** (EmailFabricante) that receives the API credentials. * You can either **create your own developer account** (fully autonomous β€” steps below), or **use the developer account your integration partner provides** (they share their CodigoFabricante and EmailFabricante with you). If your partner manages the developer account, skip Step 1 and go straight to Step 2 with the identifiers they gave you. *** ## πŸ”‘ How the connection works Contasol's API is activated from inside Contasol using a **CodigoFabricante** and the **email** linked to the developer account. Once activated, Software DELSOL emails the **API credentials**, which you then enter in the Chift connection settings. There are two ways to organize this: * **You manage your own developer account** β†’ you create it once (Step 1), receive your CodigoFabricante, and stay independent. * **Your partner manages the developer account** β†’ they give you their CodigoFabricante and EmailFabricante; the credentials email is sent to them, and they share the credentials with you. The steps below cover the autonomous path. *** # πŸ›  **PREPARATION** ## **Step 1 β€” Create a developer account** Go to the [Software DELSOL developer registration](https://www.sdelsol.com/api/) and create a developer account to receive your **CodigoFabricante**. Choose an email address you have access to β€” Software DELSOL sends the API credentials to this address. image.png image.png image.png ⚠ Use an email you actively monitor: this is where your CodigoFabricante confirmation and, later, your API credentials arrive. You will receive a confirmation email containing your **CodigoFabricante**. ## **Step 2 β€” Activate the API in Contasol** Using your **CodigoFabricante** and the **email** you registered, activate API access inside Contasol. Software DELSOL's official guide walks through each screen: [CONTASOL | Acceso por API](https://ayuda.teamsystem.es/hc/es/articles/32074527830033-CONTASOL-Acceso-por-API) image.png Once activated, you receive an email with your **API credentials**. image.png # ⚑**️** CONNECTION image.png **Step 1 β€”** Choose a **name** for your connection. *(If the connection name field isn't visible, simply skip this step and continue.)* image.png **Step 2 β€”** Enter your **Customer code** β€” the customer code received by email when activating the ContaSOL API. **Step 3 β€”** Enter your **Customer database** β€” the name of the ContaSOL company database you want to connect to. Received by email when activating the ContaSOL API. **Step 4 β€”** Enter your **Password** β€” the password received by email when activating the ContaSOL API. **Step 5 β€”** Click **Connect** to finalise the connection. image.png *** ## ❓ Troubleshooting | Issue | What to do | | -------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | No credentials email received | Check the inbox of the **exact email** registered as the developer account (EmailFabricante), including spam. Re-check the CodigoFabricante entered in Contasol matches the account. | | Connection fails in Chift | Make sure you entered the credentials exactly as received in the email, with no extra spaces. | | Using your partner's developer account | You do not need to create your own account β€” enter the **CodigoFabricante** and **EmailFabricante** your partner provided in Step 2, and ask them for the resulting credentials. | | You want to test before going live | Create a free trial account (installer + credentials valid for 1 month): [https://www.sdelsol.com/prueba-gratuita/contasol/](https://www.sdelsol.com/prueba-gratuita/contasol/) | # ⚑**️** CONNECTION **Step 1:** Choose a name for your connection.
