Export Conversions to Snap Ads
Send attributed conversions from Vendo to your Snapchat Pixel through the Conversions API, so that Snapchat can optimize your campaigns.
Last reviewed September 15, 2026
This guide shows how to send conversions from Vendo to Snap Ads. Snapchat uses the conversions to measure and optimize your campaigns.
How It Works
- The source event that you select counts as a conversion, such as a purchase.
- Vendo applies your attribution model to connect each conversion to a Snapchat ad click.
- Vendo sends each conversion to your Snapchat Pixel through the Conversions API.
Vendo matches a conversion to a click with the sccid click ID. It can also send hashed email and phone to improve the match.
Before You Start
- A Snap Ads App connected in Vendo. Vendo uses the sign-in of this App to send conversions. You do not need an access token.
- A Snapchat Pixel in your Snapchat Ads account.
- A Source that records the event that you want to count as a conversion.
- A website that keeps the
sccidparameter from the landing page URL.

- In Snapchat Ads Manager, open Events Manager.
- Select your Pixel.
- Copy the Pixel ID.
Step 2: Add the Destination
- In Vendo, go to Data > Destinations.
- Click Add Destination.
- Select Snap Ads as the destination.
- Select the Source that records your conversion event.
Step 3: Configure the Conversion
Caution: Do not select the Participation attribution model for this export. Participation gives full credit to each touchpoint. Snapchat then receives more than one conversion for each purchase, and its optimization data is wrong.
The form shows these settings in this order:
| Setting | What it does | Default |
|---|---|---|
| Conversion Count | Every sends each conversion. Use it for purchases. Once sends only the first conversion for each customer. Use it for leads. | Every |
| Deduplication Window | Shown for Every only. Vendo ignores a repeat conversion from the same customer inside this window: 4 hours, 1 day, 3 days, 1 week or 30 days. | 4 hours |
| Attribution Model | How Vendo gives credit for a conversion: Last Click, First Click, Linear, Time Decay, U-Shaped or Participation. | Last Click |
| Lookback Window | How many days of conversions each export reads again: 1, 7, 14 or 28 days. | 7 days |
| Conversion Matching | Identified Conversions sends only conversions with a click ID. Send All Conversions also sends conversions without a click ID, matched with hashed email and phone. | Identified Conversions |
| Pixel ID | The Pixel ID from Step 1. Required. | None |
| Conversion Event (Pixel Settings) | The Snapchat standard event that Vendo sends: Purchase, Sign Up, Add to Cart, View Content, Subscribe, Start Checkout, Add Billing, Search, Level Complete or App Install. Required. | None |
| Conversion Event | The source event that counts as this conversion. Select one event for each conversion action. If you leave it empty, Vendo can send every conversion event. | None |
| Conversion Mapping | Connects Snapchat fields to properties on the source event. Email and phone come from identity resolution unless you map them. | Identity resolution |
| Dynamic Value Assignment | Sends a value from a prediction model in place of the event value. If a customer has no prediction, Vendo sends the event value. | Off |
The form has two settings named Conversion Event. The one in Pixel Settings is the Snapchat event. The other one is the event from your Source.
For more information about each model, see Attribution Models.
Note: The Snapchat Conversions API can match on email and phone only.
Step 4: Check the Export
Caution: The test sends a real event to the live Snapchat API. Use a test row, not a real customer conversion, if you can.
- On the Destination page, click Test.
- Select a row from the source table.
- Click Send Test Event.
- Click Sync Now to start an export.
- Open the Conversion Log tab.
- Make sure that your conversions show the Sent status.
- If a row shows Failed, open the Logs tab to read the error.
- After Snapchat processes the events, find them in Snapchat Events Manager.
The Conversion Log shows the time, the user, the event, the source, the match type, the value and the status of each conversion.
What Vendo Sends
Vendo sends events to the /{pixel_id}/events endpoint of the Snapchat Conversions API.
| Field | Value |
|---|---|
event_type | The Snapchat standard event from Pixel Settings |
event_conversion_type | OFFLINE |
timestamp | The conversion time, as a Unix timestamp in milliseconds |
click_id | The Snapchat click ID (sccid), when the conversion has one |
hashed_email, hashed_phone_number | Hashed email and phone, when you select them |
price | The attributed conversion value |
currency | The currency of the conversion |
client_dedup_id | A stable event ID, so that Snapchat does not count it twice |
Vendo does not send a conversion that has no click ID and no selected email or phone. Snapchat cannot match that conversion.
Troubleshooting
- No conversions in the Conversion Log: make sure that your website keeps the
sccid. Also make sure that the source Conversion Event is correct. - Pixel not found: make sure that the Pixel ID is the ID of your Pixel from Step 1.
- Authentication errors: open the Snap Ads App in Vendo. If it shows Reconnect Required, connect it again.
