## Choose how Atlan connects to dbt

> Compare the two ways Atlan can read your dbt metadata - the dbt Cloud API with a token, or dbt output files in a cloud storage bucket for dbt Core.

Atlan can read your dbt metadata two ways: by calling the dbt Cloud API with a token, or by reading the files dbt produces from a cloud storage bucket (for dbt Core). This page helps you pick the right one in about two minutes - before you touch any tokens or cloud configuration.

## Before you start: Two facts you need

Everything below depends on knowing these. Gather them first - they determine which path applies to you.

| Fact | How to find it |
|---|---|
| **Which dbt you run: dbt Cloud or dbt Core** | If your team logs into a dbt website (an address like `cloud.getdbt.com` or `xx000.us1.dbt.com`) and runs jobs there, that's **dbt Cloud**. If dbt runs on your own machines or CI/CD pipeline (GitHub Actions, Airflow, Jenkins…), that's **dbt Core**. Ask whoever runs your dbt jobs. |
| **Which cloud and region your Atlan tenant runs on** (AWS, Azure, or GCP) | Ask your Atlan admin, or [raise a support request](https://docs.atlan.com/llms/platform/submit-request/submit-request/llms.txt) - say "which cloud and region is my tenant hosted in, and what's its outbound IP?" You need this if anything on your side restricts access by IP address. |

## Compare two methods

| | dbt Cloud - API token | dbt Core - storage bucket |
|---|---|---|
| **How Atlan reads metadata** | Atlan calls the dbt Cloud APIs over the internet (TLS-encrypted) using a token you create | Your dbt pipeline uploads output files (`manifest.json` etc.) to a bucket; Atlan reads them from there |
| **What you configure** | A dbt Cloud token + your dbt Cloud access URL | A bucket (yours or Atlan-managed) + read access for Atlan |
| **Network path** | Atlan → dbt Cloud API, from your tenant's fixed outbound IP | Atlan → your S3 / GCS / ADLS bucket, from your tenant's cloud identity |
| **Who is involved** | You + your dbt Cloud admin (+ Atlan support if dbt Cloud restricts by IP) | You + your cloud/infra team + Atlan support (for Atlan's identity ARN or a managed bucket) |
| **Typical setup time** | Under an hour (add 1–2 days if IP restrictions are involved) | Half a day to a few days (IAM approvals are usually the long pole) |
| **Start here** | [dbt Cloud guide](https://docs.atlan.com/llms/connectors/dbt/connect-dbt-cloud-with-an-api-token/llms.txt) | [dbt Core guide](https://docs.atlan.com/llms/connectors/dbt/connect-dbt-core-via-a-storage-bucket/llms.txt) |

> **Info: dbt Core has two storage options**
>
>
> With dbt Core you can use **your own bucket** (AWS S3, Google Cloud Storage, or Azure Data Lake Storage) or ask Atlan to provision an **Atlan-managed bucket** - you get a prefix and upload credentials, and skip most of the IAM work. Both are covered in the [dbt Core guide](https://docs.atlan.com/llms/connectors/dbt/connect-dbt-core-via-a-storage-bucket/llms.txt) and [Set up dbt Core](https://docs.atlan.com/llms/connectors/dbt/set-up-dbt-core/llms.txt).

## Which method to pick

- **You run dbt Cloud → use the API token method.** It's the direct path, and the only one that also picks up dbt Cloud job/environment context.
- **You run dbt Core → use the storage bucket method.** There is no API to call; Atlan reads the files dbt writes. If your security team is slow to approve cross-account access, the Atlan-managed bucket option avoids that entirely.
- **You run both** (common during migrations) → set up one connection per flavor. See [Special cases](https://docs.atlan.com/llms/connectors/dbt/special-cases/llms.txt) for how to avoid duplicate assets.

> **Caution: The two failure modes that dominate support requests**
>
>
> Most dbt connectivity failures are one of two things: **dbt Cloud rejecting Atlan's IP address** (when your dbt Cloud account has IP restrictions turned on - the error misleadingly mentions "token permissions"), and **bucket permission errors for dbt Core** (AccessDenied from S3/GCS). Both are covered step-by-step in the guides and in [Troubleshooting dbt connectivity](https://docs.atlan.com/llms/connectors/dbt/troubleshooting-dbt-connectivity/llms.txt).
