The script example below includes optimization parameters like caching and retry. This tutorial focuses on the essential Voucherify-specific parts. Read [Optimize your Connected Content scripts](/integrations/braze-connected-content-optimization) for details on each optimization parameter. ## Display fetched data in Braze messages Use the following steps to display the data fetched from Voucherify in Braze messages. Copy and paste the Connected Content script under the `` tag in a message HTML template. ```liquid Connected content publication script lines theme={null} {% assign braze_campaign_id = {{campaign.${api_id}}} %} {% assign customer_id = {{${user_id}}} %} {% assign source_id = braze_campaign_id | append: customer_id %} {% assign voucherify_campaign_id = "camp_XXXXXXXXXXXXXXXXXXXXXXXX" %} {% assign cache_id = source_id %} {% connected_content https://api.voucherify.io/v1/publications?cache_id={{cache_id}} :method post :headers { "X-App-Id": "12345678-90QW-ERTY-UIOP-asdfghjklzxc", "X-App-Token": "MNBVCXZL-KJHG-FDSA-POIU-ytrewq098765" } :body campaign={{voucherify_campaign_id}}&customer={{customer_id}}&channel=Braze&source_id={{source_id}} :content_type application/json :cache_max_age :retry :save publication %} ``` Add from Voucherify: * `campaign_id` copied from the campaign details view in the Voucherify dashboard (line 4). * Your API endpoint. You can check it in **Project settings** > **General** > **API endpoint** (line 8). * Add publications address `/v1/publications` and the API method (lines 8-9). Don't remove `?cache_id={{cache_id}}`, as it reduces the number of API calls. * Add your API credentials for authentication (lines 11-12). ```liquid Connected content publication script lines focus={4,8-9,11-12} theme={null} {% assign braze_campaign_id = {{campaign.${api_id}}} %} {% assign customer_id = {{${user_id}}} %} {% assign source_id = braze_campaign_id | append: customer_id %} {% assign voucherify_campaign_id = "camp_XXXXXXXXXXXXXXXXXXXXXXXX" %} {% assign cache_id = source_id %} {% connected_content https://api.voucherify.io/v1/publications?cache_id={{cache_id}} :method post :headers { "X-App-Id": "12345678-90QW-ERTY-UIOP-asdfghjklzxc", "X-App-Token": "MNBVCXZL-KJHG-FDSA-POIU-ytrewq098765" } :body campaign={{voucherify_campaign_id}}&customer={{customer_id}}&channel=Braze&source_id={{source_id}} :content_type application/json :cache_max_age :retry :save publication %} ``` Responses from the Voucherify API are stored by connected content under the value of `:save` parameter. For example, `:save publication` in line 18. ```liquid Connected content publication script lines focus={18} theme={null} {% assign braze_campaign_id = {{campaign.${api_id}}} %} {% assign customer_id = {{${user_id}}} %} {% assign source_id = braze_campaign_id | append: customer_id %} {% assign voucherify_campaign_id = "camp_XXXXXXXXXXXXXXXXXXXXXXXX" %} {% assign cache_id = source_id %} {% connected_content https://api.voucherify.io/v1/publications?cache_id={{cache_id}} :method post :headers { "X-App-Id": "12345678-90QW-ERTY-UIOP-asdfghjklzxc", "X-App-Token": "MNBVCXZL-KJHG-FDSA-POIU-ytrewq098765" } :body campaign={{voucherify_campaign_id}}&customer={{customer_id}}&channel=Braze&source_id={{source_id}} :content_type application/json :cache_max_age :retry :save publication %} ``` This enables you to retrieve and display data from a Voucherify response in Braze messages. To display the published code in a message template, create a snippet that fetches a unique code from the voucher object: ```liquid theme={null} {{publication.voucher.code}} ``` Each customer will get a message with a unique code automatically assigned to their profile. Each time the user receives a code, it is published to their profile in Voucherify. Experiment with different data fields You can fetch any field from Voucherify's response. For gift cards, you can also display gift card balance by using the following snippet: ```liquid theme={null} Your gift card: {{publication.voucher.code}}. Your balance: {{publication.voucher.gift.amount}}. ``` See [POST Create publication](/api-reference/publications/create-publication) for the full response schema. When setting up a campaign target, use advanced settings to limit the number of messages sent per minute. Rate limits protect your API quota during testing and live traffic. Uncontrolled sending can exhaust code pools or exceed API limits. Read more about rate limiting and frequency capping in [Braze documentation](https://www.braze.com/docs/user_guide/engagement_tools/campaigns/building_campaigns/rate-limiting/#delivery-speed-rate-limiting). The script is ready. Send test messages with **Test Send** before launching. Braze preview mode doesn't display Connected Content calls with a `retry` attribute. In Voucherify, go to **Audit logs** to check if Braze called the API successfully. ## Next steps Visit the following pages to achieve more with Voucherify and Braze Connected Content: * [Optimize your Connected Content scripts](/integrations/braze-connected-content-optimization) — Configure caching and retry mechanisms * [Connected Content script reference](/integrations/braze-connected-content-reference) — View all script templates
