Connecting Particle.io to Stitch is a three-step process:
Particle.io Webhook Limits
Before you dive into connecting Particle.io to Stitch, take note of the following:
- Particle.io allows a user to create up to 20 webhooks.
- A Particle.io webhook may be triggered up to 10 times per minute for every device registered to that user’s account.
Add Particle.io as a Stitch data source
- Sign into your Stitch account.
On the Stitch Dashboard page, click the Add Integration button.
Click the Particle.io 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 Particle.io” would create a schema called
stitch_particleioin the destination. Note: Schema names cannot be changed after you save the integration.
- Click Save Integration.
Generate a Particle.io Webhook URL
Once Stitch has successfully saved and created the Particle.io integration, you’ll be redirected to a page that displays your Particle.io 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 Particle.io
The last step is to setup webhooks in your Particle.io account.
- Sign into your Particle.io console.
- Click Integrations in the left nav tab.
- Click Webhook.
- In the Event Name field, enter the name of the event you want to track.
- In the URL field, paste your Stitch-generated webhook URL.
- The Request Type field should have POST selected - leave this as-is.
In the Device field, select the device you want to trigger the webhook:
- When finished, click Create Webhook.
After you’ve successfully connected your Particle.io integration, Stitch will continuously replicate your webhook data into your destination.
- Webhooks and historical data
- How data is loaded into your destination
- How to query for the latest data
Webhooks and historical data
Because Particle.io data is sent to Stitch in real-time, this means that only new records are replicated to your destination. 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 destination.
This version of Stitch’s Particle.io integration loads data in an Append-Only fashion. When data is loaded using the Append-Only behavior, records are appended to the end of the table as new rows. Existing rows in the table aren’t updated even if the source has defined Primary Keys. Multiple versions of a row can exist in a table, creating a log of how a record has changed over time. Data stored this way can provide insights and historical details about how those rows have changed over time.
Refer to the Understanding loading behavior guide for more info and examples.
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-particleio.data] o INNER JOIN ( SELECT MAX(_sdc_sequence) AS seq, [primary-key] FROM [stitch-redshift:stitch-particleio.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 Particle.io) 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 Particle.io’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 Particle.io webhook URLs at a time. These URLs contain security access tokens and as such, have access to your Particle.io 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 Particle.io section to update the webhook URL in Particle.io.
- After you’ve updated the webhook URL in Particle.io, click the Revoke button next to the oldest webhook URL in Stitch. This will invalidate the token and revoke access.
