Offer Wall Merchant Search API

offer wall merchant search api overview the offer wall merchant search api is a new single queryable endpoint that gives you real time access to wildfire's full merchant catalog — including commission rates, coupon data, merchant metadata, logos, domains, and category information — all in one response for existing clients, building an offer wall required ingesting & stitching together multiple separate json feeds managing your own caching layer, and keying records across feeds by merchant id this api aims to eliminates that entirely what you needed before what you get now merchant feed — logos, metadata, scores ✅ included in every merchant response merchant rate feed — commission rates ✅ included as maxrate, maxratekind, detailedrates coupon feed — promo codes and offers ✅ included as coupons\[] array active domain feed — merchant domains ✅ included as merchantdomains\[] category feed — category taxonomy ✅ included as categorybreadcrumbs featured merchant feed — curated top brands ✅ included as isfeaturedmerchant note the stand down policy feed is specific to browser extension compliance and is not part of this api if you are building a browser extension, you still need to consume that feed separately getting started endpoint https //api wfi re/v1/offerwall merchant/{app id}/search?q={query} replace {app id} with your wildfire client application id that corresponds with

returns a merchants array along with pagination metadata { "merchants" \[ ], "pagecount" 1, "pagesize" 100, "totalcount" 1 } merchant object each merchant in the array contains the following fields

object detailedrates contains one entry per commission tier and replaces the need to reference the merchant rate feed { "id" 383397, "name" "womens/mens clothing, and garden supplies purchases",

human readable description of what this rate applies to kind percentage or flat amount rate value as a string — parse as float boostedoffer active boost details if applicable; all zeros when no boost is active note amount is returned as a string, not a number parse it to a float before performing any calculations a value of "0" means no commission is paid on that tier coupons object the coupons

names, wrap in quotes q=merchantname "home depot" name matching is not case sensitive and matches on exact whole words partial word matches are not supported — merchantname "diabetes sto" will not return "diabetes store " find a merchant by id q=merchantid 5475228 find featured merchants q=isfeaturedmerchant\ true find merchants with active boosts q=boosted\ true filter by commission rate

maxratecurrency\ usd for a rate range q=maxrate \[5 to 10] and maxratekind\ percentage filter by category q=primarymerchantcategoryid 17 multiple categories q=primarymerchantcategoryid 17 or primarymerchantcategoryid 1 to find category ids, reference the wildfire category feed documentation or use a wildcard query (q= ) and inspect the categorybreadcrumbs in the response find merchants

newest merchants first merchantname asc alphabetical isfeaturedmerchant desc, maxrate desc featured first, then by rate example q=primarymerchantcategoryid 33\&sort=merchantscore desc wildcards q=merchantname\ mart ✅ matches mart, marty's, martini q=merchantname\ wa?mart ✅ matches walmart, wagmart q=merchantname mart ❌ leading wildcards are not supported edge cases and gotchas certain edge cases to watch out for 1 no match fallback returns all results if a query has no exact matches — for example, a name containing a special character like an apostrophe without proper quoting — the api may return all results rather than an empty set always check the totalcount field in the response a value of exactly 10000 is a strong signal that the query fell back to returning everything // incorrect — apostrophe causes a parse failure, may return all results q=merchantname\ lowe's // correct q=merchantname "lowe's" 2 case sensitivity rules different parts of the query have different casing requirements what rule example boolean operators uppercase only and, or, not range keyword uppercase only \[2025 01 01 to 2025 12 31] field names exact casing merchantname, maxrate, isfeaturedmerchant maxratekind values uppercase percentage, flat detailedrates kind values uppercase percentage, flat coupons discounttype values lowercase flat, percentage 3 date format dates must use yyyy mm dd format time components are not supported ✅ createddate \[2025 01 01 to 2025 12 31] ✅ coupons startdate >"2025 11 01" (note quotes required with > syntax) ✅ coupons startdate \[2025 11 01 to 2025 11 05] ❌ createddate \[2025 01 15t10 30 00z to ] ❌ createddate >2025 11 01 (missing quotes with > syntax) 4 numeric values require leading zeros decimal values less than 1 must include the leading zero ✅ maxrate >0 5 ❌ maxrate > 5 5 url encoding special characters in query strings must be url encoded most http libraries handle this automatically, but if you're constructing urls manually character encoded %3a > %3e \[ %5b ] %5d space + or %20 6 nested field conditions apply to the same item when filtering on multiple coupons or detailedrates fields, both conditions must be satisfied by the same nested item — not one condition per item this query finds merchants where a single coupon has both a flat discount and a discount amount greater than 20 q=coupons discountamount >20 and coupons discounttype\ flat it does not match a merchant that has one coupon with amount > 20 and a different coupon of type flat 7 nested field responses may include non matching items when a query matches on a nested field (e g coupons ), the full coupons array for that merchant is returned — not just the matching coupon(s) the response may contain coupons that do not satisfy your filter criteria always validate nested items client side before surfacing them in your ui do not assume the api has pre filtered the nested array 8 field existence check to find merchants where a field has any value at all, use field q=coupons code // merchants that have at least one coupon record q=detailedrates amount // merchants with commission rate data to find merchants where a field exists and is not empty q=coupons code and coupons code "" best practices always pair maxrate with maxratekind filtering on rate alone mixes percentage and flat values , making comparisons meaningless if building a usd only experience, also add maxratecurrency\ usd when filtering on flat rates use merchantscore desc for quality ranking when building an offer wall or category page, sorting by merchantscore desc surfaces the highest quality, most reliable merchants first filter to logoimageexists\ true for display experiences merchants without logos will result in broken ui when building any visual offer wall, add this filter to your base query validate nested coupon fields before display due to the response behavior described in edge case #7, always check that each coupon in the coupons array actually satisfies your criteria before rendering it in particular, check discounttype, discountamount, enddate, and offercurrencyid on the client check parseconfidence before surfacing coupon codes coupons with low parseconfidence (below 0 5) were parsed automatically and may have incomplete or misleading descriptions consider applying a minimum confidence threshold for display in consumer facing experiences use totalcount as a sanity check if your query returns exactly 10000 results, it likely fell back to returning all merchants due to a malformed query review your syntax before using the results paginate thoughtfully pagesize is capped at 100 for large result sets, paginate using pagenumber and use totalcount and pagecount to determine how many pages to request scope by offercurrencyid for multi region deployments coupon amounts are not always in usd if your platform serves a specific market, filter or label coupons by offercurrencyid to avoid displaying incorrect discount amounts to users common values 840 = usd, 124 = cad syntax quick reference // exact match merchantname\ walmart // multi word value merchantname "home depot" // numeric comparison maxrate >5 maxrate >=5 maxrate <10 maxrate \[5 to 10] // inclusive range maxrate {5 to 10} // exclusive range // boolean operators (must be uppercase) condition1 and condition2 condition1 or condition2 not condition1 // grouping (condition1 or condition2) and condition3 // wildcards (trailing only) merchantname\ mart // multi character merchantname\ wa?mart // single character // field existence
