}Composites
Create composite
Creates a composite at one of your plants. A composite is a manufacturer-defined mix of materials by percentage.
Idempotent create — a replay of the same Idempotency-Key returns the
original response (200); otherwise a new composite is created
(201). Your external_id must be unique: reusing one returns 409. See
External IDs.

}Authorizations
Per-manufacturer API key in the X-API-Key header, format
emidat-{key_id}-{secret} where key_id is a random public handle.
Issued by an owner in the Emidat
dashboard; carries its own permission scopes, optional plant
restrictions, and optional expiry. A revoked, expired, or unknown key
returns 401. See the Authentication guide for details.
Headers
Optional client-generated key (e.g. a UUID) that makes a create
idempotent — the only mechanism that does so. A replay carrying the same
key returns the original response unchanged (200); reusing a key with a
different request body is rejected with 409. Keys are scoped to your
manufacturer and retained for 6h. See External IDs.
Body
application/json
The plant's Emidat UUID.
Human-readable composite name. Must be unique among your active
composites at this plant; a duplicate returns 409.
Example:
"Blended Cement Mix A"
Composite category. Every material in the composite must belong to a material type allowed for this category.
Available options:
chemicals, plastics, electronics, facing_layers, glass, fittings, resins, plastics_metal, mechanical_composites, glass_chemicals, glass_carbon_reinforced_polymers, masterbatches, processed_plastics, fabrics, furniture_component Materials that constitute this composite — at least 2, no
duplicates. Percentages across all entries must sum to exactly 100.
Every material must be allowed for the composite_type.
Minimum array length:
2Show child attributes
Show child attributes
Your own composite code. Optional. When provided it is unique among
your active composites — creating another with the same code returns
409 (see External IDs).
Example:
"BLENDED_CEMENT_MIX_A"
Response
Returned unchanged — an Idempotency-Key replay.
Emidat-assigned composite UUID.
Your own code for this composite, null when none is set. Supplier
products reference the composite by its Emidat id; BOM entries
reference those supplier products, not the composite directly.
Example:
"BLENDED_CEMENT_MIX_A"
The plant's Emidat UUID.
Human-readable composite name.
Example:
"Blended Cement Mix A"
Composite category. Every material in the composite must belong to a material type allowed for this category.
Available options:
chemicals, plastics, electronics, facing_layers, glass, fittings, resins, plastics_metal, mechanical_composites, glass_chemicals, glass_carbon_reinforced_polymers, masterbatches, processed_plastics, fabrics, furniture_component Ingredients constituting this composite, with percentages summing to 100.
