Update an OTP template. This is a partial update: a field you omit keeps its stored value rather than falling back to your account default, so changing a suffix leaves the template’s code size, TTL and rate limits alone. Custom suffixes are checked before they are stored. Sending a suffix while custom suffixes are not enabled on your account is refused with custom_suffix_not_enabled. A suffix that is malformed is refused with invalid_suffix, one that reads like another company or a public institution with suffix_not_allowed, and one written in an alphabet we do not support yet with suffix_script_not_supported.

Authorizations

Authorization

string

header

required

Bearer authentication header of the form Bearer <token>, where <token> is your auth token.

Path Parameters

template_id

string

required

The identifier of the template.

Body

application/json

A partial update. Every field is optional, and a field you omit keeps its stored value.

name

string

The name of the template.

Example:

"Acme Bank"

kind

enum<string>

The kind of message the template sends.

Available options:

optimized,

psd2,

account-takeover

suffix

string

The custom text appended to the message. Requires custom suffixes to be enabled on your account.

Example:

"AcmeBank"

code_size

integer

The number of digits in the verification code, between 4 and 8.

Example:

6

ttl_minutes

integer

How many minutes a code stays valid after it was sent, between 1 and 1440.

Example:

10

max_retries

integer

How many times the end user may ask for the code to be sent again, between 1 and 50.

Example:

3

retry_delay_seconds

integer

How many seconds the end user must wait between two of those manual retries, between 1 and 3600.

Example:

30

per_phone_number_limit

integer

How many verifications one phone number may run over sliding_window_hours, between 1 and 1000.

Example:

5

sliding_window_hours

integer

The number of hours the per_phone_number_limit rate limit is measured over, between 1 and 72.

Example:

24

security_suffix_type

enum<string>

The security wording appended to the message.

Available options:

none,

basic,

expiration,

anti_phishing

max_auto_retries

integer

How many times Prelude resends the code on its own, between 1 and 5.

Example:

1

auto_expire_previous_attempts

boolean

Whether requesting a new code invalidates the codes sent before it.

Example:

true

Response

string

required

The identifier of the template, to pass as template_id when creating a verification.

Example:

"template_01k8ap1btqf5r9fq2c8ax5fhc9"

name

string

required

The name of the template.

Example:

"Acme Bank"

kind

enum<string>

required

The kind of message the template sends. Possible values are:

optimized - A standard OTP message.
psd2 - A PSD2 strong customer authentication message.
account-takeover - An account takeover confirmation message.

Available options:

optimized,

psd2,

account-takeover

code_size

integer

required

The number of digits in the verification code.

Example:

6

ttl_minutes

integer

required

How many minutes a code stays valid after it was sent.

Example:

10

max_retries

integer

required

How many times the end user may ask for the code to be sent again.

Example:

3

retry_delay_seconds

integer

required

How many seconds the end user must wait between two of those manual retries.

Example:

30

per_phone_number_limit

integer

required

How many verifications one phone number may run over sliding_window_hours.

Example:

5

sliding_window_hours

integer

required

The number of hours the per_phone_number_limit rate limit is measured over.

Example:

24

security_suffix_type

enum<string>

required

The security wording appended to the message. Possible values are:

none - No security wording.
basic - A short do-not-share warning.
expiration - The basic warning plus the code expiration.
anti_phishing - The strongest anti-phishing wording.

Available options:

none,

basic,

expiration,

anti_phishing

max_auto_retries

integer

required

How many times Prelude resends the code on its own, without the end user asking.

Example:

1

auto_expire_previous_attempts

boolean

required

Whether requesting a new code invalidates the codes sent before it, so only the most recently sent code is valid.

Example:

true

suffix

string

The custom text appended to the message. Absent when the template appends none.

Example:

"AcmeBank"

created_at

string<date-time>

The date and time when the template was created. Absent on templates created before this was recorded.
