Querying Recommendations
You can generic recommendations using the GraphQL orders endpoint. The recommendations offered here don't use sessions so they aren't personalized but still offer enough flexibility to support a multitude of use-cases.

Fetching toplists recommendations

The endpoint can be used to fetch toplist recommendations i.e. best-sellers. Toplists recommendations are either sorted by views or buys.
curl -0 -v -X POST https://api.nosto.com/v1/graphql \
-u ":<token>" \
-H 'Content-Type: application/graphql' \
-d @- << EOF
query {
recos (preview: false, image: VERSION_7_200_200) {
toplist(hours: 168, sort: BUYS, params: {
minProducts: 1
maxProducts: 10
}) {
primary {
name
productId
}
}
}
}
EOF

Fetching random recommendations

The endpoint can be used to fetch random recommendations i.e. previews. Random recommendations are a totally randomized selection of products and often used for testing purposes.
curl -0 -v -X POST https://api.nosto.com/v1/graphql \
-u ":<token>" \
-H 'Content-Type: application/graphql' \
-d @- << EOF
query {
recos (preview: false, image: VERSION_7_200_200) {
random(params: {
minProducts: 1
maxProducts: 10
}) {
primary {
name
productId
}
}
}
}
EOF

Fetching related recommendations

The endpoint can be used to fetch related recommendations i.e. cross-sellers. Cross-sell recommendations allow you fetch related products to a given set of products.
Example: If you were to use this to add recommendations to a product page, the productIds parameter would be a single-item array containing the product identifiers of the product that is being viewed.
Example: If you were to use this to add recommendations to an order-follow email, the productIds parameter would be an array containing the product identifiers of the products that were purchased.
curl -0 -v -X POST https://api.nosto.com/v1/graphql \
-u ":<token>" \
-H 'Content-Type: application/graphql' \
-d @- << EOF
query {
recos (preview: false, image: VERSION_7_200_200) {
related(relationship: VIEWED_TOGETHER, productIds: [
"8685560646"
],
params: {
minProducts: 1
maxProducts: 10
}) {
primary {
name
productId
}
}
}
}
EOF

Fetching search recommendations

The endpoint can be used to fetch recommendations related to a search term.
Example: If you were to use this to add recommendations to a search page, the term parameter would be the entire search term as queries by the user.
Note: This endpoint cannot be used for building auto-complete style integrations.
curl -0 -v -X POST https://api.nosto.com/v1/graphql \
-u ":<token>" \
-H 'Content-Type: application/graphql' \
-d @- << EOF
query {
recos (preview: false, image: VERSION_7_200_200) {
search(term: "shoes",
params: {
minProducts: 1
maxProducts: 10
}) {
primary {
name
productId
}
}
}
}
EOF

The map of product attributes used for inclusion or exclusion
discounted: Boolean

fresh: Boolean

price: InputPriceParams

tags1: [String]

The second set of tags used for inclusion or exclusion
tags3: [String]
The third set of tags used for inclusion or exclusion
exclude field expect type InputFilterParams whose attributes are:

categories: [String]

customFields: [InputAttributeParams]
The map of product attributes used for inclusion or exclusion
discounted: Boolean

Here is an example of a query including filters
curl -0 -v -X POST https://api.nosto.com/v1/graphql \
-u ":<token>" \
-H 'Content-Type: application/graphql' \
-d @- << EOF
query {
recos (preview: false, image: VERSION_7_200_200) {
toplist(hours: 168, sort: BUYS, params: {
minProducts: 1
maxProducts: 10
include: {
customFields: [
{
"attribute": "pattern"
"values": "Solid"
