Banco Inter Empresas Tutorial

How to create an API integration in Banco Inter Empresas to obtain the Client ID, Client Secret, key, and certificate needed to connect with Pluggy.

To connect your Banco Inter Empresas account to Pluggy, you first need to create a data-sharing authorization inside Inter's own Internet Banking.

This authorization is done by creating an API integration within your account.

After creating this integration, Banco Inter will provide:

  • Client ID
  • Client Secret
  • Key file ("Chave Key")
  • Certificate ("Certificado")

These four pieces of information will be used to connect your Inter Empresas account with Pluggy.

Information required for the connection:

  • Client ID
  • Client Secret
  • Key file (.key)
  • Certificate file (.crt)

(see figure):

How to create the integration in Banco Inter#

To create your application and obtain your access credentials (Client ID, Client Secret, key file, and certificate), follow the instructions below:

Step 1 — Access Internet Banking#

  • Log in to your Banco Inter Empresas account here;
  • After authenticating via QR code, you will be taken to your account's home page.

Step 2 — Open the integrations menu#

In the top menu of the home page:

  1. Click Integrar (Integrate)
  2. Select Integrações (Integrations)
  3. Click Nova integração (New integration)

Step 3 — Create the new integration#

On the Nova integração (New integration) screen, fill in the fields:

  • Nome da integração (Integration name) Enter a name of your choice
  • Descrição (Description) Enter a description of your choice

Then click: Próximo (Next)

Step 4 — Define the integration scope#

On the Nova Integração via API (New API Integration) page, you will need to select the integration's permissions.

Expand the menu:

API Banking

Select the option:

  • Consultar extrato e saldo (Query statement and balance)

Then click: Criar Integração (Create Integration)

Optional functionality

If you also want to issue boletos through the API, select:

  • API Cobrança (Boleto + Pix) (Billing API — Boleto + Pix)

Step 5 — Additional authentication#

An additional authentication screen will be displayed.

Banco Inter will send a 6-digit code via SMS to the registered mobile phone.

Enter the received code to continue.

Step 6 — Fill in the integration form#

After authenticating, the following message will appear:

  • Integração criada com sucesso (Integration created successfully)

Click: Preencher formulário (Fill in the form)

Banco Inter uses this form to better understand how the integration will be used.

You will need to fill in information about:

  • Your customers' activity

  • Company information

  • Company field of operation

Fill in the data according to your company's real information.

When you are done, submit the form.

Step 7 — Wait for Banco Inter's review#

After the form is submitted, Banco Inter may perform a validation of the information.

In that case, a message will be displayed informing you that:

  • Seus dados estão em análise (Your data is under review)

Click: Acessar minhas integrações (Access my integrations)

Step 8 — Download the key and certificate#

On the Minhas integrações (My integrations) screen:

  1. Locate the integration you created (by the name and description defined earlier).
  2. Check the integration's status.

Possible statuses:

  • Em validação (Under validation) → wait for approval
  • Novo (New) → the credentials can now be downloaded

If the status is Novo (New):

  1. Click the three dots
  2. Select the option: Download chave e certificado (Download key and certificate)

Step 9 — Confirm the credentials download#

A warning will be displayed informing you that:

  • ⚠️ The key and certificate can only be downloaded once.

After reading the instructions, click:

Sim, baixar (Yes, download)

Step 10 — Save the credentials#

After confirming the download:

  1. A screen will display:
    1. Client ID
    2. Client Secret

⚠️ Save this information immediately, as it will not be shown again.

Step 11 — Extract the key and certificate files#

A ZIP file containing the integration files will also be downloaded.

Extract the ZIP file.

After extraction you will have two files:

  • Inter_API_Chave.key → API key
  • Inter_API_Certificado.crt → API certificate

These files will be used in the connection with Pluggy.

The integration will go through a validation process; after a few minutes its status will be updated to Ativo (Active) and it will be ready to use.

Final step — Connect in Pluggy#

Now open the Pluggy widget and enter the integration data.

Fill in the fields:

  • Client ID Paste the generated Client ID
  • Client Secret Paste the generated Client Secret
  • Key (.key) Upload the file: Inter_API_Chave.key
  • Certificate (.crt) Upload the file: Inter_API_Certificado.crt

Then click the Conectar (Connect) button.

Your Banco Inter Empresas account will be connected to Pluggy.

Done! The integration has been completed successfully.
