Benchling Integration
When to use
Use this skill for Benchling registry entities, sequence imports, inventory, ELN entries,
workflow tasks, apps, event-driven integrations, and warehouse analytics.
Reviewed 2026-09-30: examples target the released benchling-sdk 1.25.0 and its
stable v2 API models. The
recommends V3 for new development, while the
still describes endpoint-specific early access. Confirm your tenant's V3 availability and
stability before migrating; these v2 SDK examples must not be mechanically rewritten to V3.
SDK imports, model serialization, and request construction were checked locally against
1.25.0. Tenant-dependent examples are illustrative: no authenticated requests,
mutations, AWS deployment, or warehouse connection were run.
Workflow
Identify the tenant, API version, identity, and permissions. Use OAuth app credentials
for background integrations; use delegated authorization when acting as an individual
user. See authentication.
Read the relevant schema and resolve actual folder, registry, status, and dropdown IDs.
Preserve sequence alphabet/topology and sample units. A valid Python model does not
establish biological correctness or satisfaction of a tenant's required fields.
Read a small filtered page before writing. Use typed SDK methods and check their
actual parameter names; not all services share the same CRUD naming convention.
Construct and serialize a representative payload. For imports, retain external IDs
and returned Benchling IDs so a retry can reconcile a partial run without duplicates.
Perform the requested operation and read back the result. Check terminal async status;
completed polling can still mean FAILED.
Setup and a read-only query
uv pip install "benchling-sdk==1.25.0"
import os
from benchling_sdk.benchling import Benchling
from benchling_sdk.auth.client_credentials_oauth2 import ClientCredentialsOAuth2
tenant_url = os.environ["BENCHLING_TENANT_URL"].rstrip("/")
benchling = Benchling(
url=tenant_url,
auth_method=ClientCredentialsOAuth2(
client_id=os.environ["BENCHLING_CLIENT_ID"],
client_secret=os.environ["BENCHLING_CLIENT_SECRET"],
token_url=f"{tenant_url}/oauth/token",
),
)
for page in benchling.dna_sequences.list(page_size=10, name_includes="plasmid"):
for sequence in page:
print(sequence.id, sequence.name)
break # deliberate first-page connectivity/permission check
A successful empty page is a valid connectivity result. It does not imply access to
all projects. There is no documented v2 users/me route or SDK users.get_me().
Important SDK conventions
Import fields from benchling_sdk.helpers.serialization_helpers. Its input is
{"field_name": {"value": value}}, including the inner value mapping.
Use dna_sequence_id for DNA updates and workflow_task_id for workflow updates.
Workflow task creation requires a workflow_task_group_id.
Entry methods are create_entry, get_entry_by_id, list_entries, and update_entry.
list() usually returns pages; iterate twice to reach the objects. estimated_count
is a property that can raise NotImplementedError, not a method or guaranteed count.
Moving a tube uses ContainerUpdate(parent_storage_id=...). Material transfer is a
separate operation; it changes contents and quantities.
Register on creation with registry_id plus eitherentity_registry_id (a human
registry identifier) ornaming_strategy. Do not confuse those with the registry's ID.
Common use cases
Import FASTA sequences
Install Biopython separately (uv pip install biopython). This illustrative import
creates unregistered linear DNA; choose topology and resolve collisions before running.
from Bio import SeqIO
from benchling_sdk.models import DnaSequenceCreate
for record in SeqIO.parse("sequences.fasta", "fasta"):
payload = DnaSequenceCreate(
name=record.id,
bases=str(record.seq),
is_circular=False,
folder_id="lib_example",
)
created = benchling.dna_sequences.create(payload)
print(record.id, created.id) # persist this mapping for restart/reconciliation
Audit inventory under a location
for page in benchling.containers.list(ancestor_storage_id="box_example"):
for container in page:
print(container.id, container.name, container.barcode)
ancestor_storage_id includes descendants. For immediate children only, inspect the
returned parent storage or use the documented storage-contents service.
Export sequences for one schema
import csv
with open("sequences.csv", "w", newline="", encoding="utf-8") as handle:
writer = csv.DictWriter(handle, fieldnames=["id", "name", "bases", "length"])
writer.writeheader()
for page in benchling.dna_sequences.list(schema_id="ts_example"):
for seq in page:
writer.writerow({
"id": seq.id, "name": seq.name,
"bases": seq.bases, "length": len(seq.bases),
})
