# Retail & ecommerce > Integrating with Talon.One gives you full flexibility to build personalized promotions and loyalty programs for your retail or direct-to-consumer brand. Manage your omnichannel promotions with a single engine that covers ecommerce websites, mobile apps, in-store kiosks, and point of sale systems in real time. > For the complete documentation index, see [llms.txt](https://docs.talon.one/llms.txt). The following use cases and integration approaches for ecommerce outline how to use Talon.One to drive customer acquisition, increase basket size, and maximize lifetime value. ## Use cases ### Discounts and promotions #### Personalized coupon campaign Use [customer profile](/docs/product/applications/display-customer-profiles.md) data to set up incentives that target dormant customers. A fashion brand can create a coupon campaign to award these customers a discount on latest-season apparel based on their current [loyalty tier](/docs/product/loyalty-programs/profile-based/use-loyalty-tiers). Customers who spent more previously and were in a higher tier get a 15% discount, while those who made a one-time purchase and are in a lower tier get 10% off. #### Strategic product discounts Create [cart item filters](/docs/product/rules/cart-item-filters/overview) to ensure that a promotion is available for eligible products only, and set a [budget](/docs/product/campaigns/settings/manage-campaign-budgets) to ensure the campaign stays within financial limits. Using these strategic discounts, high-end electronics retailers with a diverse product range can drive sales while maintaining brand exclusivity. #### Gift with purchase (GWP) Drive customer engagement by incorporating themed deals and non-monetary rewards or experiences into your ecommerce and in-store promotional strategy. For example, create a campaign with a promotion rule that awards customers a free gift item upon purchase. When a customer spends over €40, Talon.One responds with an [effect](/docs/product/rules/effects/available-effects#incentives) that awards them a free tote bag. #### Multibuy offers and BOGO campaigns Boost sales of a single item by using cart item filters for cart-level discounts. For example, a sports brand can create an [item campaign](/docs/product/campaigns/overview#item-campaigns) that gives customers 5% off if they buy two sets of tennis balls and 10% off if they buy three sets. The campaign can include a [session budget](/docs/product/campaigns/settings/manage-campaign-budgets) to limit how many times the discount can be applied per purchase per purchase. You can also use cart item filters to set up a [Buy one, get one free (BOGO) campaign](/docs/product/tutorials/coupons/buy-3-pay-2) where a customer purchases one or more items at full price and receives the cheapest item for free. #### Cross-category bundle deals Use [bundles](/docs/product/rules/create-and-manage-bundles) to group shopping cart items and create a cross-category discount. For example, a jewelry brand can run a promotional campaign that offers customers a $20 discount if they purchase a jewelry set consisting of a bracelet and a pair of earrings. ### Loyalty programs #### Profile-based loyalty program Reward individual customers for purchases and brand interactions using a [profile-based loyalty program](/docs/product/loyalty-programs/profile-based/profile-based-overview) where customers earn points for every euro spent. Create [subledgers](/docs/product/loyalty-programs/use-subledgers) to set up separate point balances for a customer, for example, to specify that points earned in a store can only be redeemed at that same location. Points earned through a specific campaign can be configured to expire within a defined timeframe, encouraging the customer to redeem them quickly. #### Loyalty cards Unify online and offline transactional behavior using [loyalty cards](/docs/product/loyalty-programs/card-based/create-loyalty-cards) that several users can share. Members of an omnichannel beauty loyalty program can earn points through online purchases or directly in-store via [point of sale](/docs/dev/technology-partners/pos/overview) (POS) systems. You can also award points for desired customer behavior that matches your brand values. #### Personalized tier-based offers Control which promotions a customer sees based on their [loyalty tier](/docs/product/loyalty-programs/profile-based/use-loyalty-tiers) status. Gold tier members get exclusive offers invisible to lower tiers; Platinum members get 24-hour early access to flash sales. Members with negative points are restricted from high-value discounts. ### Display prices with strikethrough labels Use [strikethrough pricing](/docs/product/rules/strikethrough-pricing) to power real-time promotional data directly on your product listing pages (PLP) and product detail pages (PDP) to drive top-of-funnel conversion and urgency before a customer adds an item to the cart. Display updated prices and information directly on your online marketplace, for example, ~€100~ €80 or `20% off`. You can also use [custom effects](/docs/product/account/dev-tools/manage-custom-effects.md) to generate additional information, for example, that the price displayed is a `members price`. ## API endpoints The average API response time is under 60 ms for most [Integration API](/docs/dev/integration-api/overview.md) requests, making Talon.One a highly reliable solution. The endpoints you work with depend on your use case, but these are generally the most relevant endpoints for retail and ecommerce integrations: | Endpoint | Description | | -------- | ----------- | | [Update customer session](/integration-api#tag/Customer-sessions/operation/updateCustomerSessionV2) | Update the customer session with the latest data when the customer completes a purchase. | | [Update customer profile](/integration-api#tag/Customer-profiles/operation/updateCustomerProfileV2) | Update a customer profile, and set custom attributes, for example, transaction type or account type. You can also use this endpoint to modify the audience in which the customer is a member. | | [Track advanced event](/integration-api#tag/Events/operation/trackEventV3) | Trigger custom events on specific customer actions and act on them. For example, award loyalty points when a customer submits a product review within 30 days of purchase. | | [List customer data](/integration-api#tag/Customer-profiles/operation/getCustomerInventory) | Display user data. For example, display user rewards or integrate with a reward wallet where users can view available coupons, points, or giveaways. | | [List customer's loyalty transactions](/integration-api#tag/Loyalty/operation/getLoyaltyProgramProfileTransactions) | Display user transaction logs for loyalty programs. | ## Concepts Here's an explanation of some specific Talon.One concepts that are relevant for retail and ecommerce: | Concept | Description | | ------- | ----------- | | [Cart items](/docs/product/account/dev-tools/manage-cart-item-catalogs.md) | Shopping cart items added to an order.
