Alpha release

This source is currently in alpha. The interface and available tables may change.

The Microsoft Dynamics 365 connector syncs accounts, contacts, leads, and more into the PostHog data warehouse, so you can analyze them alongside your product data.

Prerequisites

Credentials that can read the data you want to sync. PostHog only reads data, so read access is enough.

Adding a data source

  1. In PostHog, go to the Sources tab of the data pipeline section.
  2. Click + New source and click Link next to this source.
  3. Enter your credentials (see Configuration below) and click Next.
  4. Select the tables you want to sync, choose a sync method and frequency, then click Import.

Once the syncs are complete, you can start querying this data in PostHog.

Sync your Dynamics 365 (Dataverse) customer data - accounts, contacts, leads, opportunities, cases and activities - .

To connect, register an app in Microsoft Entra ID and add a client secret. Then add that app as an application user in your Dynamics 365 environment (Power Platform admin center > Environments > Settings > Users + permissions > Application users) and give it a security role that can read the tables you want to sync. The environment URL is the one you use to open the app, for example https://contoso.crm.dynamics.com.

You'll be asked for:

  • Environment URL: for example https://contoso.crm.dynamics.com.
  • Directory (tenant) ID: for example 72f988bf-86f1-41af-91ab-2d7cd011db47.
  • Application (client) ID: for example 00001111-aaaa-2222-bbbb-3333cccc4444.
  • Client secret

Sync modes

Each table can be synced in one of several modes, depending on what the source supports:

  • Webhook (when available) – the source pushes changes to PostHog in real time. Fastest freshness, lowest ongoing cost, and the only mode that reliably captures updates and deletes.
  • Incremental – only new or updated rows are synced on each run, using a cursor field (such as an updated_at timestamp). Cheaper than a full refresh, but deletes aren't captured.
  • Append only – new rows are appended using a cursor field; existing rows are never updated. Ideal for immutable, append-only tables like event logs.
  • Full refresh – the whole table is reloaded on every sync. Use it when a table has no reliable cursor or when you need deletions reflected.

See sync methods for a full explanation of how each mode works and how to choose between them.

All Microsoft Dynamics 365 tables are full refresh. Each sync replaces the contents of the table.

Troubleshooting

  • If the connection fails with an authorization error, the client secret is wrong, expired, or has been revoked. Create a new one, then reconnect the source.
  • If a table syncs no rows, the credential may not have access to that data. Check its permissions, then reconnect the source.

If your sync is failing or data looks wrong, see the Data warehouse troubleshooting guide. If that doesn't help, contact support – we're happy to help.
