# MD for: https://www.mercadopago.com.ar/developers/en/docs/mp-delivery/catalog-management/check-publication.md \# Check publication status When importing a catalog, it is important to ensure that the process is completed successfully. To do this, make a GET request to the endpoint \[/proximity/integration/v1/catalog/{publication\_id}\](https://www.mercadopago.com.ar/developers/en/reference/mp\_delivery/\_proximity\_integrationcatalog\_publication\_id/get) with the following values: \* \`publication\_id\`: This information is obtained from the response of the catalog import endpoint. \* \`access\_token\`: This information should be included in the header. It corresponds to the user who received the publication. The access\_token can be generated through the OAuth authentication process. Refer to the \[OAuth documentation\](https://www.mercadopago.com.ar/developers/en/docs/mp-delivery/additional-content/security/oauth/introduction) for more information. This endpoint can return the following states in the response: | State | Description | |---|---| | processing | The catalog is being processed. | | error | The publication process was canceled due to an unrecoverable error. | | success | The catalog has been published. | > WARNING > > Important > > Since the catalog upload process is asynchronous, you should use the endpoint \[Check Publication Status\](https://www.mercadopago.com.ar/developers/en/reference/mp\_delivery/\_proximity\_integrationcatalog\_publication\_id/get) to verify if the catalog was imported successfully. If there is an error in the validation of this publication, we recommend implementing a retry mechanism.
