Added

• Brands API
  • Create, read, update and delete brand logos, colors, buttons and social groups, e.g. $client->Brands->createBrandLogo(), $client->Brands->getBrandColor(), $client->Brands->updateBrandButton(), $client->Brands->deleteBrandSocialGroup().
  • Read and update brand voice with $client->Brands->getBrandVoice() and $client->Brands->updateBrandVoice().
  • Read and update brand email defaults with $client->Brands->getBrandEmailDefaults(), $client->Brands->getBrandEmailDefault() and $client->Brands->updateBrandEmailDefault().
  • Requires the brands:read and brands:write scopes.
• Text Messaging API
  • Create and retrieve senders with $client->TextMessaging->createTextMessagingSender(), $client->TextMessaging->getTextMessagingSenders() and $client->TextMessaging->getTextMessagingSender().
  • Track and resubmit sender registrations with $client->TextMessaging->getTextMessagingSenderRegistration() and $client->TextMessaging->createTextMessagingSenderRegistration().
  • Create and retrieve your account's text messaging configuration with $client->TextMessaging->createTextMessagingConfiguration() and $client->TextMessaging->getTextMessagingConfiguration().
  • Requires the sender-config:read and sender-config:write scopes.
  • For more information, see our Text Messaging API overview.
• Templates API
  • New send test email endpoint $client->Templates->createTemplatePreviewSendJob() sends a test email of a template to one or more recipients. Requires the templates:write scope.
• Billing Usage API
  • Read your account's current-period metered usage against plan caps with $client->BillingUsage->listBillingUsage() and $client->BillingUsage->getBillingUsage(). Requires the usage:read scope.
• Translations API
  • List, retrieve, create, update and delete translations with $client->Translations->getTranslations(), $client->Translations->getTranslation(), $client->Translations->createTranslation(), $client->Translations->updateTranslation() and $client->Translations->deleteTranslation().
  • New relationship endpoints retrieve the campaign variation, flow message, email template or template universal content associated with a translation.
• Forms API
  • New update form endpoint $client->Forms->updateForm().
  • New publish and unpublish endpoints $client->Forms->publishForm() and $client->Forms->unpublishForm().
• Flows API
  • New create flow action endpoint $client->Flows->createFlowAction(). Place the new action after an existing action, before an existing action, or as the first action in a flow that has none. Requires the flows:write scope.
• Universal Content API
  • New clone endpoint $client->Templates->cloneUniversalContent(). Requires the templates:write scope.
• Campaigns API
  • The campaign audience, campaign variation and campaign scheduling endpoints are now generally available, including scheduling one message or all messages in a campaign.
  • $client->Campaigns->createCampaign() now accepts a partial structure. Send a campaign with only some of its audiences, messages and variations and add the rest with the individual endpoints, or still send the full structure in one request.

Changed

• Breaking: Campaigns API now uses the omnichannel model
  • Affects getCampaigns(), getCampaign(), createCampaign(), updateCampaign(), createCampaignClone(), and the campaign message endpoints including getCampaignMessage() and updateCampaignMessage(). Request and response shapes have been replaced.
  • A campaign is now a container with defaults for send timezone, send strategy and exit conditions. It has one or more audiences, and each audience has one or more messages.
  • A campaign no longer has a channel, and getCampaigns() no longer requires a channel filter.
  • Each message belongs to one audience and sends on one channel. Each message has one variation, which holds the channel-specific content. A/B tests are not supported.
  • The relationship from a campaign message to its campaign now returns the omnichannel campaign.
  • If you used the omnichannel beta, request and response shapes are unchanged. The include=campaign parameter on the campaign message endpoints is fixed.
  • For more information, see our Campaigns API overview.
• Breaking: Universal Content blocks and sections have a new display_options shape
  • Universal content now supports all block types and sections, where only seven block types were supported before.
  • If you read or write display_options through getAllUniversalContent(), getUniversalContent(), createUniversalContent(), updateUniversalContent() or deleteUniversalContent(), update your code.
  • For more information, see our Universal Content API overview.
