|Configurable Replication Methods||
Connecting Mandrill to Stitch is a three-step process:
- Add Mandrill as a Stitch data source
- Define the Primary Key
- Generate a Webhook URL
- Set up webhooks in Mandrill
Important: Setup prerequisites
To set up Mandrill, you need:
Add Mandrill as a Stitch Data Source
- Sign into your Stitch account.
On the Stitch Dashboard page, click the Add Integration button.
Click the Incoming Webhooks icon.
Enter a name for the integration. This is the name that will display on the Stitch Dashboard for the integration; it’ll also be used to create the schema in your destination.
For example, the name “Stitch Mandrill” would create a schema called
stitch_mandrillin the destination. Note: Schema names cannot be changed after you save the integration.
Define the Primary Key
Next, you’ll define the Primary Key for the data that your Mandrill integration will send to your data warehouse. A Primary Key is a field that’s used to uniquely identify each message in the webhook data.
Primary Keys must:
- Uniquely identify each message in the webhook data
- Have field names with 50 or less characters
Be top-level fields. This means that Primary Key fields can’t be part of a nested object or array.
If you need help determining if a field is part of a top-level record, we recommend looking for examples of the JSON record in your app’s API documentation. We’re always happy to help if you still aren’t sure.
Primary Keys and Replication Methods
Defining a Primary Key is optional, but the Incremental Replication Method Stitch uses to update your webhook integration’s data will depend on whether a Primary Key is provided or not.
- If a Primary Key is provided, replication to webhooks data will take place via an upsert. This means that existing rows can be updated.
- If a Primary Key is NOT provided:
- Replication will be Append-Only.
- Stitch will auto-generate a field called
_sdc_primary_keyto be used as a Primary Key. This is because Stitch requires a Primary Key to replicate and de-dupe data.
Additionally, we don’t recommend changing a Primary Key once the integration has been set up and data has replicated. This could result in fields not being updated properly.
Enter the Primary Key into Stitch
In the Primary Key field, enter the name of the field you want to use as a Primary Key. Note that this field isn’t required, but if left blank Stitch will auto-generate a Primary Key instead.
Generate a Mandrill Webhook URL
Once Stitch has successfully saved and created the Mandrill integration, you’ll be redirected to a page that displays your Mandrill webhook URL and token (which is blurred in the image below):
Click the Copy button to copy it.
Note that this particular URL won’t display in Stitch again once you click Continue. Think of this URL like you would your login or API credentials - keep it secret, keep it safe. You can, however, generate another URL should you need it.
Once you’ve copied your webhook URL, click Continue to wrap things up in Stitch.
Set up webhooks in Mandrill
The last step is to setup webhooks in your Mandrill account.
- Sign into your MailChimp account. (Yes, you read that right!)
- Click the user menu (your icon) > Account.
- Click the Transactional tab.
- Click Launch Mandrill.
- Once you’re in the Mandrill app, click the Settings icon in the left nav tab.
- Click the Webhooks tab.
- Click Add a Webhook.
Check the events that you want to track. Every time one of these events occurs, the webhook will be triggered and data will post to your webhook URL:
- In the Post to URL field, paste the Stitch-generated webhook URL.
- Enter a brief Description.
- When you’re finished, click Create Webhook.
After you’ve successfully connected your Mandrill integration, Stitch will continuously replicate your webhook data into your data warehouse.
Webhooks and historical data
Because Mandrill data is sent to Stitch in real-time, this means that only new records are replicated to your data warehouse. Most webhook-based integrations don’t retain historical data due to this as-it-happens approach.
In the event that our webhook service experiences downtime, you may notice some lag between an event occurring and the data appearing in your data warehouse.
This version of Stitch’s Mandrill integration uses Append-Only Replication. Append-Only Replication is a type of Incremental Replication where newly replicated data is appended to the end of a table. Existing rows are not updated - updates are added to the end of the table as new rows. Data stored this way can provide insights and historical details about how those rows have changed over time.
Query for the latest data
If you simply want the latest version of the object - or objects, if you elected to track more than one during the setup - in the integration’s table (
data), you’ll have to adjust your querying strategy to account for the append-only method of replication. This is a little different than querying records that are updated using
updated_at Incremental Replication.
To do this, you can use the
_sdc_sequence column and the table’s Primary Key. The
_sdc_sequence is a Unix epoch (down to the millisecond) attached to the record during replication and can help determine the order of all the versions of a row.
Note: If you didn’t define a Primary Key while setting up the integration, the Primary Key for the table will be
If you wanted to create a snapshot of the latest version of this table, you could run a query like this:
SELECT * FROM [stitch-redshift:stitch-mandrill.data] o INNER JOIN ( SELECT MAX(_sdc_sequence) AS seq, [primary-key] FROM [stitch-redshift:stitch-mandrill.data] GROUP BY [primary-key]) oo ON o.[primary-key] = oo.[primary-key] AND o._sdc_sequence = oo.seq
This approach uses a subquery to get a single list of every row’s Primary Key and maximum sequence number. It then joins the original table to both the Primary Key and maximum sequence, which makes all other column values available for querying.
In v1 of the Stitch Incoming Webhooks integration, Stitch will create a single table - called
data - in the webhook integration schema (this will be the name you enter in the Integration Schema field when you set up Mandrill) of your data warehouse.
The schema of this table will contain two “types” of columns:
- Columns used by Stitch (prepended with
- Columns sent by the provider’s webhook API
Aside from the Stitch columns, the schema of this table will depend entirely on Mandrill’s webhook API. With the exception of the
_sdc fields, Stitch does not augment Incoming Webhooks data nor does it have any control over the fields sent by the webhook provider.
Webhook URLs & Security
Stitch allows you to generate up to 2 Mandrill webhook URLs at a time. These URLs contain security access tokens and as such, have access to your Mandrill account.
If you ever need to change your webhook URL, you can do so in the Integration Settings page after the integration has been created:
- Click into the integration from the Stitch Dashboard page.
- Click the Settings button.
- In the Webhook URLs section, click the Generate Webhook URL button.
- A new webhook URL will display. Press the clipboard icon to copy it.
- Follow the steps in the Setting Up Webhooks in Mandrill section to update the webhook URL in Mandrill.
- After you’ve updated the webhook URL in Mandrill, click the Revoke button next to the oldest webhook URL in Stitch. This will invalidate the token and revoke access.
